New Electrochemistry Probeware and HPLC Connectivity

August 1, 2006

In keeping with its tradition of innovation and leadership in teaching lab data acquisition, MeasureNet is introducing exciting new probeware for electrochemical titrations and High Pressure Liquid Chromatography (HPLC). These new capabilities expand MeasureNet efficiency beyond General Chemistry into advanced lab environments.

Commercially available by the end of 2006, new electrochemistry electrodes will allow users to perform potentiometric and amperometric titrations. A single dual platinum-wire electrode will perform both amperometric and potentiometric acquisitions with the simple swapping of an adapter. Current and voltage settings for the probe can be set directly at each MeasureNet workstation.

Examples for potentiometry are the titration of Fe2+ with Ce4+ on dual platinum electrodes at constant current or the determination of chloride with silver nitrate using one indicator and one reference electrode at zero current.  The amperometric technique will complement the potentiometric method. Examining a particular redox system with various techniques allows a critical evaluation and comparison of each method and its suitability for the particular analysis.

MeasureNet is also adding High Pressure Liquid Chromatography (HPLC) connectivity using the Buck Scientific BLC-10 and BLC-20 models. The cost-effective BLC-10 Series Systems have very sensitive filter photometers for routine assays at the most common wavelengths: 254, 280, 365, 420, 505, and 540nm. It includes a pump and injector for instant analyses. The instrument features a completely integrated design for full functionality and, like MeasureNet, has a small footprint that saves space on lab benchtops. The BLC-20 Series Analytical HPLC systems use a high-quality, precision monochromator-based spectrophotometer for a full range of wavelengths (190-800nm) for selective analyses integrated into a complete LC package. The BLC-20 also is easily upgraded to a gradient system. Both BCL-10 and BLC-20 models boast accuracy of 1% maximum deviation and <0.5% RSD precision.

The BLC-10 and BLC-20 HPLCs offer significant capability and value versus traditional high-end brands, particularly when efficiently shared via a MeasureNet network using MeasureNet’s web-based data storage feature. HPLC connectivity will be available beginning in December, 2006.

MeasureNet Technology Ltd. manufactures patented, network-based data acquisition interfaces for science teaching laboratories. It is a spin-off of the University of Cincinnati's Department of Chemistry and is headquartered in Cincinnati, Ohio. Measurenet's award-winning, PC-reducing design helps reduce laboratory maintenance and operational costs while giving students access to high quality shared UV-vis spectroscopy, gas chromatograph connectivity, and an array of innovative probeware. Its acclaimed intuitive design provides improved transparency to enable better science-focused, not technology-focused, learning. Winner of the Ohio Governor's Award For Excellence in Energy Efficiency, MeasureNet networks are found in universities, community colleges, high schools, and vocational training centers across the United States and around the world.
