Russell Mainstream Supply are proud to announce the launch of the new EconoRUSH retractable electro-chemical sensor holder, designed to allow the replacement of electrochemical sensors without interrupting the process flow, greatly reducing down time and maintenance. The EconoRUSH utilises the Ingold 25mm port system, a unique gimbal mounting and o-rings with a low compression set. The majority of the components are constructed of 316L stainless steel.
With the EconoRUSH sensor holder installed, sensors can be easily replaced and returned to measuring mode in a matter of seconds, without shutting down the process.
Any sensor (pH, DO, conductivity, etc) with a diameter of 12mm and a working length of 120mm (below the cap) can be used.
The EconoRUSH sensor holder is currently designed to receive sensor caps with 13.5 PG threads, although other types can be accommodated.
The only stipulation is that the 'measuring' end of the sensor maintains a 12mm diameter beyond the o-ring seals.
The sensors are mounted in the holder with a unique (patent pending) gimbal system, designed to prevent stress points at the sensor cap/body juncture.
Firstly, the o-ring and washer that come attached to the sensor need to be removed as they are not required.
Secondly, the gimbal is threaded onto the sensor until it fully seats.
The sensor/gimbal assembly is then fitted into the holder, past the o-ring seals at the front.
Finally, the gimbal nut is threaded onto the holder.
It can now be seen that the gimbal freely 'floats' within a spherical chamber.
Any misalignment between the sensor cap and body, or bowing in the body, does not result in applied stress to the sensor, as is the case with fixed thread systems.
The gimbal assembly also allows for threads other than 13.5 PG to be used.
A simple, economical change of gimbal design is all that is required.06

Thermo Electron has introduced the 2006-2007 edition of the chromatography Columns and Consumables Catalogue, which consolidates the full breadth of the Thermo chromatography consumables into a single collection. Included is the enhanced line of HyperSep SPE products, the new state-of-the-art Hypersil Gold HPLC column family, and Trace capillary GC columns and consumables. The expanded 300+ page catalogue is the perfect laboratory resource for product selection, technical reference information and application support in the pharmaceutical, chemical, biochemical, environmental, food and beverage industries and many more.
The new catalog provides comprehensive guidance on the practice of chromatography techniques along with more than 400 applications to help users make informed column choices.
This detailed product selection guide will be available in January 2006.
To receive the catalogue, please order a copy via the website.
The Thermo HyperSep SPE benefits users by enabling rapid, effective and economical sample preparation.
They are available in a range of formats including solid phase extraction columns, multiwellplates and pipette tips.
Based on highly pure silica, Hypersil Gold columns provide excellent symmetrical peaks, even when analysing compounds that give notoriously poor peak shape on traditional C18 or L1 chemistries.
In addition to the C18 phase, Hypersil Gold columns are now offered in C8, CN, PFP (pentafluorophenyl) and aQ (polar endcapped C18) phases, as well as in a 1.9 micron particle size in selected chemistries.
Trace GC columns feature high temperature stability and low phase bleed, achieving high quality and performance.
The columns cover a range of polarities from the TR-1 100% dimethyl polysiloxane to the TR-fame 70% cyanopropyl polysilphenylene-siloxane phases, offering application-focused solutions.

Crystal clear, clinically pure, no bacteria and no particles: this would be an ideal sample for ion chromatography. Unfortunately things are often very different in real life. Apart from the ions to be determined, the samples still contain large amounts of aggressive substances that make an analysis difficult if not impossible, were the sample to be determined directly.
Samples with a high load can destroy the separating columns or block the capillaries, pump valves or the detector.
This is why critical samples require a thorough sample preparation procedure.
However, manual sample preparation means longer processing times, sometimes combined with poorer reproducibility, inaccurate results and high costs.
Metrohm now provides you with a range of possibilities and methods that allow you to automate sample preparation and make it considerably more efficient than was previously possible.
The costs are reduced dramatically, the quality of the results is improved significantly and the field in which ion chromatography can be used as a powerful analytical method is extended considerably.
A new 20-page full-colour brochure provides, from simple filtration, ultrafiltration, solid-phase extraction to dialysis, dilution, preconcentration, etc, an easy to read yet complete overview of the entire range of MISP: Metrohm Inline Sample Preparation systems.

The determination of the content of surface-active agents (surfactants) plays an important role in many sectors - from wastewater analysis up to quality control in production processes
A new DIN/EN standard method has been announced for determining anionic surfactants by means of potentiometric two-phase titration. The determination of the content of surface-active agents (surfactants) plays an important role in many sectors - from wastewater analysis up to quality control in production processes. A method that is still in widespread use is the so-called Epton titration according to ISO 2271, a complicated and time-consuming manual titration.
The new DIN EN 14480 standard now describes an alternative determination method that is much simpler and faster: potentiometric two-phase titration.
Potentiometric two-phase titration according to DIN EN 14480: more precise, faster and much healthier! The solution of the anionic surfactant is pipetted into a titration vessel, to which a two-phase mixture of water and methyl isobutyl ketone/ethanol 1 : 1 and an emulsifier are added.
Under vigorous stirring the emulsion formed is titrated with a cationic surfactant, in this case benzethonium chloride (Hyamine 1622).
The ion pair formed, which is insoluble in water, is extracted immediately into the organic phase.
The determination of the equivalence point does not take place visually, but potentiometrically using surfactant-sensitive electrodes.
The Surfactrodes from Metrohm are used for this purpose; they have a high affinity for surface-active agents.
In comparison with the Epton titration you profit from the following advantages.
* Use of unproblematic solvents instead of chloroform.
* Short determination times: only a few minutes per titration.
* Objective, computer-supported determination of the equivalence point and therefore improved precision.
* Can easily be automated.
In an extensive Europe-wide interlaboratory test the potentiometric two-phase titration was compared with the Epton method and was found to yield the same analytical results with a better repeatability.

Nonaqueous titrations play a key role in monitoring product quality in many areas, including the pharmaceutical, oil, and plastics industries, as well as in edible oils and fats. The Metrohm Solvotrode combination pH glass electrode has been specially designed for use with non-aqueous acid-base titrations. This new electrode makes complicated titrations easier because it can be used in many applications where it was previously necessary to use three and four electrode systems due to electrostatic interferences.
The pH glass membrane of the Solvotrode is designed with special low-impedance glass, shaped in a relatively large sphere, which results in very stable measurements, even in poorly conducting solutions.
The inner electrolyte tube of the Solvotrode is coated with a special conductor that ensures an optimally shielded reference system, regardless of the electrolyte level.
This additional shielding is particularly important for non-aqueous measurements and titrations since it will virtually eliminate static electricity interferences.
The built-in reference electrode is equipped with a removable PCTFE (polychlorotrifluoroethylene) ground-joint diaphragm that is easy to clean and less sensitive to contamination or blockage.
This new electrode also uses the Metrohm 'Long Life' reference system: an Ag/AgCl cartridge with a silver ion barrier that ensures an extended life and consistent measurements.

The Metrohm 811 Online IC is designed to provide optimum IC analysis in accordance with industry standards. This means ease of operation, perfect reliability even in rough environments, minimum external supply requirements, high data security and, of course, precise and reproducible results. More than a decade ago Metrohm started to develop instruments for plants that rely on the results of online titration to control their production processes.
Requirements like uninterrupted power supply and the separation of electronic, mechanical, and wet-chemistry parts of the instrument were implemented.
When Metrohm started to build online IC systems it was able to profit from the wealth of experience already gained from the online titration system.
Even though the 811 Online IC was presented for the first time at Pittcon 2001, it is an instrument that benefits from Metrohm's experience in online analysis.
The 811 Online IC can be custom-tailored to any IC application.
The standard version is a one-channel instrument that allows analysis of either cations or anions.
The dual-channel version is designed to analyse cations and anions simultaneously.
Every line is equipped with a 10-port manifold valve.
This valve can be set up to take samples out of 10 permanently purged lines.
For every single sample stream a freely defined number of ions can be analysed and monitored.
Special control cards show at a glance whether the values are inside the required concentration ranges.
The IC system itself consists of the standard components that have been used for many years in the modular Metrohm IC systems.
The conductivity detector is temperature-stabilised to better than 0.01 C and located in a Faraday cage.
Pre-amplification occurs inside the detector block.
As a result, signal noise is minimal while sensitivity is very high.
These features are especially beneficial when trace amounts of anions or cations have to be analysed.
The whole system is designed to require very little maintenance.
The costs of ownership are low due to the practically unlimited lifetime of the suppressor, the relatively cheap eluents, the long lifetime of the columns and the long service intervals for the pumps.
The 811 Online IC brings online analysis to a new level of performance.
It defines new standards concerning price-performance ratio, simplicity of use, reliability and quality of the analytical results.

New from Metrohm is the 845 Eluent Synthesizer incorporating valid ICT which guarantees cost effective, certified reagents fully controlled by computer and completely GLP compliant
Preparation of mobile phases for Ion chromatography (IC) and High Performance Liquid Chromatography (HPLC) can be time consuming and for semi skilled workers there is the very real possibility of errors occurring. One way to ensure batch to batch reproducibility is to buy in a previously prepared certified reagent as generation of eluents by electrolytic means requires the use of costly replacement cartridges and more importantly it cannot be certifiable by the very nature of the way in which the eluent was produced. New from Metrohm comes the 845 Eluent Synthesizer incorporating Valid ICT which guarantees cost effective, certified reagents at the touch of a button fully controlled by computer and completely GLP compliant, with the production of a certificate that documents the preparation procedure and all the production data.
The 845 Eluent Synthesizer allows the possibility of preparing an infinite variety of different solutions, dilutions and mixtures for use as eluents, standards, buffer solutions or reagents for any chemical application.
The solutions can be organic or inorganic, ionic or non ionic, aqueous or non aqueous, virtually anything required by the application - be it IC or HPLC based - is feasible.
The 845 Eluent Synthesizer allows work in research, analysis and quality assurance and the automation helps to reduce the costs compared to the historical manual preparation of eluents or those done by electrolytic generation.
The fully automatic system guarantees reproducibility of precise mixtures and helps avoid errors by virtue that all the calculations are performed by the instrument itself in volumes, moles or milligrams.
The automated procedure is based on proven Dosino technology which allows high precision dosing to be carried out with the option of pH modification if required.
The 845 Eluent Synthesizer is controlled by the Mix Control software where particular emphasis has been given to the ease of operation though the use of pictograms.
The valid ICT interface produces a freely definable report once production of the reagent has been completed that contains all the necessary GLP compliant documentation.
An audit trail records every working step providing additional security and traceability and each method can be signed electronically.
Many chemical manufacturers offer chemicals that are recommended for use with Valid ICT for the production of certified IC eluents and this can be concentrated solutions in either bottle or bag form.
In the simplest case when full certification is not required, then the concentrates can be prepared from the solid buffer salt.
In the case of preparation of standards, Metrohm recommends the use of Primust, a unique primary standard for IC and a collaboration between Metrohm and Fluka with the Materials Testing and Research Institutes of BAM (Germany) and EMPA (Switzerland).
The 845 Eluent Synthesizer has been favourably priced to offer all institutions the opportunity to benefit from this fully certifiable analytical solution that is available with either a single Dosino for one mobile phase (or other reagent) or two Dosinos for the production of two mobile phases (eg anion and cation eluents).
For the opportunity to discuss the advantages that certifiable reagent production from Metrohm provides, please contact our friendly support team.

Acid pickling is usually the final cleaning stage prior to plating and is the removal of scale (surface oxides) and other contaminants such as dirt and films from chemical immersion. Another benefit of pickling is that the metal surface is activated ready for plating and a light etch is achieved that helps provide a better adhesion to the substrate. Historically the plating company performed a manual wet titration, 3 times a day, to determine the acid content of the pickling bath and then an excess (approximately 240 litres) of concentrated hydrofluoric/nitric acid was added manually over a 24 hour period to ensure that the acid content of the bath did not fall below a desired limit and hence suitable quality control was maintained.
Metrohm with more than 60 years experience in the field of Ion Analysis has developed a method for determination of the acid content of pickling baths using Ion chromatography (IC).
Metrohm Online IC is designed for continuous 24-7 use throughout the year (with minimal time spent offline for maintenance) that is supplied in an industrial housing and can be custom-tailored to the application.
Special control cards show at a glance whether the values are inside the required concentration ranges giving increased security and environmental control.
With the 821 Compact Online IC from Metrohm it was possible to tighten the pickling process and reduce the amount of concentrate added to the pickling bath to ensure that the acid content remains within specification.
The Online IC takes a measurement from the pickling bath using a recycling loop every 30 minutes and calculates the acid content based upon the amount of fluoride and nitrate present.
Depending upon the result, either no action is taken, or if the acid content is low a defined amount of concentrate is added to the pickling bath using an external pneumatic pump system controlled using an output from the Online IC.
The advantages of the Metrohm Online IC is that there is less human interaction (ideal as the solutions utilised are extremely concentrated acids), a result is obtained every 30 minutes instead of every 8 hours and concentrate is added to the pickling bath only when it is required - when the acid bath falls below 8% - instead of adding excessive amounts of concentrate thereby reducing the running costs of the raw materials.
Dilution of the concentrated acid is performed inline using the time proven Metrohm Dosino liquid handling technology and a small amount of sample injected onto the separation column required for the Ion Analysis.
The Online IC system consists of top class components that have been used for many years in the Metrohm laboratory IC systems and can be operated with ease by non-chemists.
No sample preparation is required as the multi-selection valve handles the automation and sampling of the streams of interest.
For the opportunity to discuss tighter process control in an industrial environment using Online IC, please contact Metrohm UK, where our friendly support team will be delighted to discuss your project requirements and provide additional information.

The Ecotrode Plus is ideal for routine titrations: the result from the titration is only as good as the electrode you use - any investment in a titrator is negated if an inferior electrode is used
Metrohm is the market leader in titration, however, any investment in a titrator is negated if an inferior electrode is used. In short, the result from the titration is only as good as the electrode you use. The Ecotrode Plus is ideal for routine titrations! The continually increasing success of our Unitrode and Aquatrode Plus range in pH measurement shows that the fixed ground joint is being recognised as the universal diaphragm type.
It is largely insensitive to contaminants and requires only minimal maintenance.
The fixed ground-joint diaphragm is suitable for a wide range of samples, from clear, ion-deficient solutions up to highly concentrated suspensions or emulsions.
Its greatest strength, however, is its precision: The fixed ground-joint diaphragm allows low-noise potential measurements that are only dependent on the ionic strength and stirring speed to a minimal extent, thus meeting crucial requirements for a rapid and precise titration.
In order to utilise the advantages of the fixed ground-joint diaphragm to the full extent in titrations, a new type of membrane glass has also been developed for the Ecotrode Plus, which, in addition to a short response time, exhibits very high endurance.
In short: a membrane glass that does not give up easily, even in continuous use.
The 6.0262.100 Ecotrode Plus is the result of 60 years of experience, ultra-modern production technology, the made in 'Switzerland' label, and our continuous striving to optimise our products.
In many ways this new Metrosensor represents a clear improvement of our well-proven 'workhorse', the 6.0232.100 Ecotrode.
Until the 30th June, the Ecotrode plus is offered at a discounted price of GBP99.

A completely new regression analysis module along with further improvements to HPLC system control, document management and summary table reporting are the headline features of Laura 3.4, the latest release of the LabLogic radio-chromatography data collection and analysis software. Regression analysis makes it possible for UV HPLC users to configure quality QC and calibration standards in a method, and to analyse and produce reports on calibration data. Like the previous release, Laura 3.4 can control pumps, auto-samplers and other components of the HPLC system as well as the detector itself, eliminating the inconvenience of maintaining several programmes.
Jasco systems can now be controlled in this way.
The document management facility, which supports Word 2003, has been improved by the addition of versioning, so that the complete development history of a report can be tracked and different versions compared; and the summary table function is now more configurable, including further options for generating graphs.

Advanced electronics with a measuring amplifier the size of a postage stamp means that it fits into the Titrando titrator electrode cable head
Thanks to the most advanced electronics Metrohm has been able to reduce the measuring amplifier to the size of a postage stamp, which means that the complete measuring amplifier fits into the electrode cable head. Directly in the sensor, the analogue/digital converter of the latest generation in the iConnect converts the analogue measuring signal into a digital data flow. Digital data transmission means that the measuring signal is no longer susceptible to electrostatic influences.
With the iConnect the sensor and measuring amplifier are always calibrated together and the calibration data stored in the intelligent electrode.
As the measuring amplifier is no longer built into the instrument, the electrode and iConnect can be used together with different titrators.
The calibration procedure is no longer associated with a particular titrator.
Intellegent Titrators feature.
* Touch Control with large color screen.
* Automatic electrode recognition with intelligent sensors.
* iConnect - measuring amplifier with digital data transmission through any length of cable.
* Intuitive operation.
* Intelligent dosing elements.
* Potentiometric, Karl Fischer and STAT titration.
* Monitored dosing in synthesis labs.
* Uninterrupted dosing in tandem operation.

This chip is present in every 807 Dosing Unit.
The Titrando automatically reads from it all the data that it needs to carry out the titration properly, ie type of reagent, titer, last titer determination, shelf-life data and much more.

The Metrohm 743 Rancimat is a modern, PC-controlled analytical instrument for the comfortable determination of the oxidation stability of Biodiesel. In addition to other alternative fuels such as ethanol, methanol or biogas (methane), fatty acid methyl esters are increasingly being found on the market; these are also known as biodiesel or FAME (fatty acid methyl esters). Fatty acid methyl esters are relatively unstable on storage, as like all natural oils and fats they are slowly oxidised by atmospheric oxygen.
The substances produced in this way could cause motor damage.
This is why the oxidation stability is an important quality criterion for biodiesel; it is regularly determined during the production process.
The use of alternative fuels from renewable vegetable sources has become increasingly widespread in recent years, as the life cycle of biogenic fuels is neutral with respect to CO2 release.
The carbon dioxide released has already been assimilated from the atmosphere during plant growth.
In contrast to fossil fuels, biogenic fuels neither contribute to the accumulation of CO2 in the atmosphere nor to global warming.
In addition, alternative fuels are biodegradable and thus less environmentally harmful.
The oxidation stability of fatty acid methyl esters has already been included in various test methods as a standard parameter used to define the minimum quality requirements of biodiesel.
