A recent article,
originally published in "Innovations in Food Technology" (November, 2011), has
been made available online at ScionHasArrived.com. Authored by Zicheng Yang
& Kefei Wang, experts from Bruker's Chemical and Applied Markets division
(Fremont, California) the article explores the globalization of food supplies,
and discusses how manufacturers and other businesses are coping with the
extensive need for food testing. This increased testing is as a consequence of
contamination and spoiling incidents exposed by media coverage, as well as
consumer concerns. Surveillance has been stepped up by Governments and
regulatory agencies, with locally produced food as well as imports under
scrutiny.
Laboratories
involved in the detection and identification of contaminants and trace-level
compounds in food are challenged with an ever increasing list of compounds
under scrutiny. With daily sample load increasing, many labs are looking for an
easy to use solution that can improve turn-around time, and at the same time
improve sensitivity and maintain assay robustness.
This article
describes a gas chromatography mass spectrometry (GC-MS/MS) approach for
detection of 258 pesticides in a vegetable matrix after extraction using the QuEChERS
(Quick Easy Cheap Effective Rugged and Safe) method. The ease of method set-up,
and the sensitivity, linearity and precision of the GC-MS/MS system are
demonstrated.
