IS 10629 : 1983 Methods for determination of Aldicarb residues in crops, soil and water

1 Scope

1.1 This standard prescribes spectrophotometric and gaschromatographic methods for the determination of aldicarb[2-Methyl-2-(methylthio) propionaldehyde 0-(methylcarbamoyl) oxime]residues in crops, soil and water. The residues determined includealdicarb, its sulfoxide and the sulfones.

1.1.1 Spectrophotometric method may be adopted as a limit testfor routine purposes with the minimum detection limit of 0.1 �g/g (0.1 ppm) whereas gas chromatographic method shallbe the reference method with the minimum detection limit of0"005/�g/g (0.005 ppm).
