Identification of organochlorine pesticides in crude extracts by mass spectrometry

Abstract

A method is described for identifying a chlorinated pesticide in crude extracts (i) at 1 ppm by low resolution mass spectrometry with the aid of a recently developed temperature controlled probe and (ii) at 0.01 ppm by high resolution techniques using a photoplate record to determine the mass deficient ions containing chlorine.

This analytical method is feasible wherever ions of the same elemental composition as those derived from an unknown are not otherwise present in the crude extract mass spectrum.
