1.1 This standard prescribes spectrophotometric and gas chromatographic methods for the determination of aldicarb [ 2-Methyl-2-( methylthio) propionaldehyde 0-( methylcarbamoyl) oxime ] residues in crops, soil and water. The residues determined include aldicarb, its sulfoxide and the sulfones.
1.1.1 Spectrophotometric method may be adopted as a limit test for routine purposes with the minimum detection limit of 0.1 /μg/g (0.1 ppm) whereas gas chromatographic method shall be the reference method with the minimum detection limit of 0.005/μg/g ( 0.005 ppm ).
