✦ Synopsis

A method for the detection of organophosphorous pesticides directly on thinlayer chromatograms is described. One approach involves heating the chromatogram for a definite period of time at a specific temperature.

The other requires spraying the chromatoplate with a strong acid or base prior to the heat-treatment.

From a total of thirty-five organophosphorous pesticides investigated, twelve gave positive results. Instrumentat limits of detection at the nanogram level are possible.
