GC-MS of Pesticides in High-Chlorophyll Samples

Martin Perkins

18th July 2014

At the recent European Pesticide Residues Workshop in Dublin, Richard Fussell of the UK Food and Environment Research Agency (FERA) presented a poster showing the results of some preliminary work that he had carried out using a GERSTEL MultiFlex GC/Q-TOF.

Richard was investigating the potential of Automated Tube (liner) Exchange (ATEX) as a way of reducing the problems of poor analytical robustness when analysing for pesticide residues in green food products. Problems due to a build-up of involatile material in the GC inlet are all too common.

ATEX enables fairly crude extracts to be injected into a disposable micro vial that is operated so that involatile material doesn’t reach the GC inlet. This means that the instrument should be able to operate for extended periods without maintenance.

Initial work looks promising and you can obtain a copy of Richard’s poster here.

If you want to learn more about ATEX, we have a system working in our Cambridge laboratory and we would be happy to show it to you.
