Detector Switching System

Analysis of Pesticides Using the Detector Switching System

Quite often a lab's pesticide target list contains analytes from a variety of compound classes. Each compound class has an optimal selective GC detector that will provide the lowest detection limit and the best quantitative results. To optimally test for each of these compounds across the various classes traditionally required multiple injections on to multiple analytical lines. With the advent of Detector switching system these analyses can now be combined into a single run. Using this system it is now possible to make just one injection, separate the pesticide compounds using the appropriate column then heart-cut each compound to one of two selective detectors for optimal detection and quantitation.

The FPD selectively detects organophosphate pesticides, while the ECD offers high-sensitivity analysis of chlorinated pesticides. Even residual pesticide analysis for many target components can be efficiently and accurately handled by a single analysis.
