Thermo Fisher Scientific Inc., the world leader in serving science, today announced powerful liquid chromatography – tandem mass spectrometry (LC/MS/MS) food safety testing solutions and applications to help laboratories meet increasingly stringent monitoring requirements, simplify analyses and boost productivity. The solutions and applications will be displayed at the Salt Palace Convention Center Salons 250BCEF, May 24 – May 26, 2010 during the ASMS Conference on Mass Spectrometry and Allied Topics in Salt Lake City, Utah.
Increasing food safety concerns have resulted in more stringent global regulations for the detection of contaminants worldwide. This is especially true in Europe(EU) and Japan, where regulations for pesticides are now among the strictest, with maximum residue levels (MRLs) allowed in food products set at 10 ppb for most compounds. At the same time, the number of regulated contaminants has grown considerably. As a result, labs must quickly and accurately screen and quantitate a growing number of contaminants in extremely complex matrices at increasingly lower levels. These trends are driving the need for more sensitive, fast and cost-effective LC/MS and LC/MS/MS solutions.
“Our scientists and engineers have made remarkable progress in developing new food safety testing solutions that enhance laboratory productivity by automating and simplifying sample preparation steps and methods, and by enhancing overall system sensitivity,” said Dipankar Ghosh, strategic marketing manager for environmental and food safety solutions at Thermo Fisher Scientific. ”For example, with the new Thermo Scientific EQuan MAX, we now offer a comprehensive solution enabling laboratories to screen and quantify both target and non-target contaminants in beverages, in a single analytical run, in just minutes.”
Thermo Scientific Exactive with Accela U-HPLC increases confidence in results, meets lower MRLs
The Exactive with the Thermo Scientific Accela U-HPLC is a robust, easy-to-operate and cost-efficient LC/MS system for routine screening of pesticides. The Exactive leverages proven Thermo Scientific Orbitrap technology to deliver ultra-high-resolution (up to 100,000 FWHM) accurate-mass full-scan data that enables identification of unknowns and increases confidence in results. The Accela U-HPLC system improves chromatographic resolution, speed and sensitivity.
A new method was recently published which uses the combined Exactive and Accela system to detect 510 pesticides in food at low ppb levels in minutes. The method demonstrates excellent linearity over the range of 1-250 ppb, with correlation coefficients for the majority of pesticides greater than 0.99. Limits of quantification (LOQs) ranged from 1 – 50 ppb, and for 499 pesticides LOQs are at or below the MRL of 10 ppb imposed by EU and Japanese regulations.
