Pesticide residues - detection of grains and grains

Determination of 475 pesticide and related chemical residues in grains by gas chromatography-mass spectrometry (GC-MS). This standard specifies the method for the determination of 475 pesticide and related chemical residues in barley, wheat, oats, rice, and corn (see Appendix A) by gas chromatography-mass spectrometry. This standard is applicable to the determination of 475 pesticides and related chemical residues in barley, wheat, oats, rice, and corn. The detection limit of this standard method is 0.002 5 mg/kg -0.800 0 mg/kg (see Appendix A). 2 Normative References: The clauses in the following documents become clauses of this standard through reference in this standard.
