FOR IMMEDIATE RELEASE October 21, 2003. ESA has announced a new applications note that describes and illustrates how coulometric array detection can provide valuable additional complimentary capabilities to researchers using MS or LC/MS systems. Expanding the utility and applications of Mass Spectrometers … ESA has announced a new applications note that describes and illustrates how coulometric array detection can provide valuable additional complimentary capabilities to researchers using MS or LC/MS systems. Today, Bioanalytical groups are under pressure to provide quick, and accurate assessments of an ever-increasing number of samples. Such analyses can be complicated by inherent properties of different compounds that make them difficult to ionise for detection by MS, or may be difficult to visualise due to ion suppression effects. The application note demonstrates how ESA CoulArray electrochemical systems have been used to oxidise or otherwise react 'problem' compounds to enable them to be seen in an MS system. In addition, by using some of the unique properties of the CoulArray system, the note illustrates how it is possible to mitigate the ion suppression effects of some compounds. Simple-to operate and control the CoulArray is easily integrated with almost any Bioanalytical MS system. Fully compatible with high throughput operation the CoulArray system requires minimal maintenance to provide continuous, repeatable high performance.
