KF Coulometric Titrator for Trace Water in Battery Materials

JMScience announces their new AQUACOUNTER® Karl Fischer Coulometric Titrator (AQ-2200S). This new high-end titrator with its excellent capability and upgraded performance is ideal for the trace level water content determination in lithium-ion battery materials with high accuracy using coulometric Karl Fischer titration. Lithium-ion batteries are one of the most popular for portable electronics due to their good energy-to-weight ratios, no memory effect and a slow loss of charge when not in use. Elevated levels of water content in three primary functional components (anode, cathode, electrolyte) may cause degradation in capacity and may reduce the overall lifetime of batteries.

It will be of interest for users who: 1) have many kinds of samples to be analyzed; 2) exchange KF reagents frequently or after each measurement; 3) are eco-minded and budget-conscious.

This titrator allows two titration stations to run parallel with various coulometric/volumetric combinations. With both a volumetric and coulometric channel, one can measure moisture over the entire range from 1 ppm to 100% or double your sample throughput with 2 identical KF stations. The new design is economical and ecological because it reduces the use of expensive KFreagents. Three types of electrolytic cells are available including small volume, standard, and one-room cell. There is an ultra-trace moisture measurement mode equipped in this titrator with an accuracy of ≤10µgH20.   The new cell design allows for easy assembly and maintenance. The new 7.5-inch color touch screen is easy to read and operate. It has enhanced memory capacity and user may store results on a USBmemory stick. The stored data can be read out on the color display. Result data with curves may be viewed on a PC internet browsing program with optional software. This titrator comes equipped with a built-in thermal printer with easy paper loading and high resolution printouts. It can be used with peripherals of previous versions.

A Highly Versatile Workflow Solution for Quantitative Protein Analysis

Agilent Automation Solutions has announced a new white paper entitled 'An introduction to High-throughput Microchromatography' which introduces a highly versatile quantitative sample preparation technique for protein analysis.

The biotherapeutic industry is driving an ever-increasing demand for protein analysis. Liquid chromatography is a well proven, highly robust and versatile general technique for protein purification from complex samples, for both analytical and preparative applications. A significant challenge has been to adapt liquid chromatography to the requirements of high throughput analysis. To accomplish this, a number of critical technical requirements for scale, throughput, quantitative binding and elution, controlled flow rate, air entrainment, and microplate format must be met.

The new white paper describes how the Agilent Bravo for Protein Purification Liquid Handling Platform together with AssayMAP high throughput microchromatography system was designed specifically to meet all of the technical requirements for quantitative sample preparation for protein analysis. The AssayMAP system is comprised of a microchromatography cartridge, special associated labware, and a liquid handling device designed to interface with the cartridge and provide precise flow control in a 96-channel microplate format.

The authors describe how applications of high throughput microchromatography for protein analysis are designed to purify, quantitate and react. In purification, the goal is to separate the target protein from all or most of the impurities present in the sample, isolating the target for further operations. In quantitation, the goal is to measure the amount of the target protein present in the sample. In reaction, the goal is to modify the target protein chemically by either enzymes or other reactants. Sample preparation protocols may involve any or all of these types of steps.

A protein purification information kit including the white paper is available on request from the Agilent Automation website** or by contacting your local Agilent sales office.

From stand-alone units to fully integrated systems, Agilent Automation Solutions teams key sample preparation and creative walk-away automation approaches with personalized customer service to provide complete solutions for your laboratory.  Combining innovative engineering with high standards of quality, Agilent designs and manufactures high-performance equipment for processes that are revolutionizing pharmaceutical, biotech, and genomic research.

Versatile Handheld FTIR for QA/QC Applications

A2 Technologies, a leading supplier of FTIR analyzers for QA/QC applications in the lab, in the field or at the production line, has expanded the sampling capability of its Exoscan handheld FTIR system.  

A new Spherical ATR Sampling interface enables the Exoscan to quickly and accurately analyze a wide range of materials typically encountered in the QA/QC lab, or at the production line.  These materials include powders and granules as well as large samples such as polymer, composite and plastic sheets. 

The new design makes ATR measurements using the Exoscan easy and minimizes the need for pressure devices to achieve high quality reproducible spectra.  Two versions of the Spherical ATR are available.  Exoscan's diamond ATR is an ideal universal interface for a broad range of solid materials, while the germanium ATR is well suited to the analysis of carbon black filled rubber or samples for which measurement of thin layers on the surface is critical.

The Exoscan adds the spherical ATR capability to its other sampling technologies which include diffuse reflectance for absorbing or scattering samples, specular reflectance for coatings on reflectance surfaces and grazing angle reflectance for the measurement of very thin layers on metal surfaces.  These sampling interfaces can be interchanged in seconds, making Exoscan an ideal QA/QC analyzer for industries that must analyze measure a wide assortment of materials either in the lab, in the field or at the production line.

Graham Miller, president of A2 Technology comments:  "FTIR's role in QA/QC has been traditionally a lab based effort where sample sets are brought to the instrument.  With the development of the Exoscan, FTIR can take a role in quality assurance and quality control of products that are too large to be brought to the lab or otherwise cannot be effectively sampled.  The development the spherical ATR enables Exoscan to quickly and reliably provide high quality measurements on a broad array of materials and surfaces."

For more information on Exoscan's expanded sampling capability for lab and field use, please contact contact A2 Technologies on +1-203-312-1100 (Headquarters) / +44-7765-970-210 (Europe / Asia) or email info@a2technologies.net.

Determination of organic carbon and nitrogen in marine sediments

Exeter Analytical has published an optimised technique for direct determination of organic carbon and nitrogen in marine sediments.

The filter based technique, using an Exeter Analytical Model 440 CHN Elemental Analyser, provides rapid and routine analysis of marine sediments, results are expressed in micrograms of Carbon and Nitrogen detected simplifying the calculation process. Analytical sensitivity is less than 1 microgram.

The Exeter Analytical Model 440 is a static combustion system, with a unique horizontal furnace design, which enables easy removal of filter and sample ash between each sediment analysis.  Consequently one combustion tube will analyse in excess of 1000 sediment samples without the need for removal and cleaning.  In addition the Model 440 provides the capacity to process filters up to 47 mm in diameter in one analytical cycle.  By comparison other elemental analysers, employing vertical furnace designs, need cleaning after as little as 20 samples and larger filters have to be sub sampled several times and then corrective calculations made to enable analysis.  Effectively eliminating troublesome residue build-up the gas flow characteristics of the Model 440 analyser are superior to other elemental analysers thereby providing longer-term calibration stability as well as enhanced accuracy and precision for measured sample data.

As the Exeter Analytical Model 440 provides complete control over combustion parameters it is able to reproducibly achieve 100% combustion with the widest range of sediment samples. For sediment samples with low levels of Nitrogen in the 0.1-0.2% range, proprietary Nitrogen analysis software uniquely enables accurate measurement at these levels with a high degree of accuracy.

Sample preparation for residue analysis of pesticides

Sample preparation for residue analysis of pesticides
Sample cleanup with gel permeation chromatography (GPC) is a commonly used method in environmental and food analysis. It is a powerful way to increase the limit of detection to levels required for analysis of pesticide residues and other trace impurities. Well-established GPC sample cleaning methods such EN 12393, EN 1528, and US EPA SW-846 Method 3640A are quite time-consuming and solvent-intensive procedures. In this application note, the often used Bio-Beads SX-3 stationary phase is compared with the new EuroClean GPC material regarding performance and suitability for environmental and food laboratories. KNAUER's EuroClean GPC is shown to provide a significantly improved performance over Bio-Beads, allowing for a 30% increase in speed and solvent savings in the range of 30% ...  see more at:

All high pressure components are ASME rated and protected by a rupture disc for safe operation. These laboratory bench top models are ideal for applications where repetitive use makes convenience a necessity, such as catalytic studies, polymerization, hydrogenation, oxidation, isomerization, and dehydrogenation. All sizes are supplied as ready-to-use instruments requiring only utility connections prior to operation. The reactors are compact instruments that fit easily into a fume hood. Their modular design makes it simple and cost-effective to alter the unit’s basic configuration to adapt to new or evolving application needs.

All functions for the HPR Series Reactor are controlled by choices of two integrated processors (RxTrol Jr. or RxTrol Sr.) with a full color touch screen.  RxTrol Jr. consists of (2) temperature sensors (wall/interior mounting), and fuzzy logic PID temperature controls and mixing controls in a table top assembly.  RxTrol Sr. offers many more advanced features utilizing a microcontroller to perform all PID, ramp/soak, process trending, and interlock functions. 

Additional options include vessel windows (<150 degrees Celsius operation only), additional ports, cooling coils, sample loops, stand alone pressure transducers, supercritical fluids pumps and reagent addition modules.

Alternative Method for Chromatography Invented to Measure Medical Doses

Iranian researchers at the University of Kashan used carbon paste electrodes modified by gold nanoparticles to measure the atenolol medicine doses. This method can be an alternative for the complicated and expensive chromatography methods.

Atenolol is an effective drug for the treatment of blood pressure, angina pectoris and cardiac attacks and arrest. Excessive use of atenolol causes toxicity within the patient's body. Therefore, the determination of the dose of atenolol is of great importance in medical and clinical researches.

"Among the advantages of the electrode products in this research, mention can be made of its relatively low price in comparison with other electrodes, non-toxicity, ease of production, extensive potential range of application, low background flow, quick response, resistance against mechanical damage, perfect modifiability and sustainable surface," Mohsen Behpour, member of the Scientific Board of University of Kashan, told the Iran Nanotechnology Initiative Council.

"Those electrodes are used to determine atenolol in anti blood pressure tablets and biological liquids (urinate sample and blood serum)."

"In order to produce modified carbon paste electrodes, we first mixed some graphite powder with the colloidal solution of gold nanoparticles, and then dried it. Next, we added some paraffin oil to the mixture and loaded the obtained paste into polyethylene syringe. At the end, we made an electric connection to the paste by putting a copper wire inside the syringe," Dr Behpour said, elaborating on the procedure of the research.

Non-modified electrodes that were produced through this method have a much lower sensitivity.

"The results of this research can provide the laboratories with a simple and cost-effective method to be replaced with complicated and expensive chromatography methods," Behpour concluded.

New mobile apps

I am currently investigating the possible opportuinities to create applications for mobile phones and devices such as iPad, but rather than just develop these ideas with my publishing colleagues, I feel it makes more sense to ask the community what features they would like to see - what would benefit them the most and make people's working lives easier.
I realise that everyone is busy, but should you have a spare five minutes, I'd appreciate some input.
Please send your ideas to me at: analyticalchemistry@elsevier.com
