Pesticide residue analysis by oxygen flask combustion,by shaking an alkaline solution contained in the flask and analysis of the resulting solution followed. This procedure has been modified by . (1960) and . and . (1961) for direct combustion of evaporated crop extracts containing chlorinated pesticides.

Connotation

The use of fluorometric measurements for determination of pesticide residues,he residue chemist to explore every possible means of physical detection which is applicable to submicrogram quantities of material. The use of fluorometric methods is of value in this field because it is possible to measure accurately quantities of material which are onlv a tenth, a hundredth, or e

Pesticide residue analysis by microcoulometric gas chromatography, combination of these methods has not been used previously. Coulson .. (1960) have developed a singularly rapid and sensitive method through instrumentation for the determination of pesticide residues containing halogen or sulfur, making use of these principles. The microcoulometric gas chromatograp
