Fractionation Standards (EV-2000 AC)

Fluvalinate and chinomethionate were previously used as fractionation standards. In Food Sanitation Law #1003001 (Oct 3, 2006), section two states "Analytical method with GC/MS for multi-residues" and "Analytical method with LC/MS for multi-residues" in crops and animal products. In the method, acrinathrin and tricyclazole were used as fractionation standards. Compared to the fluvalinate and chinomethionate fractionation area, the one obtained by acrinathrin and tricyclazole is wider.
