Sample Preparation

100 µL of each standard was combined with 400 µL acetonitrile (final volume 1 mL) for a final concentration of 60 ppm. The sample was pipetted into a 2 mL short-cap, screw-thread vial (cat.# 21143) and capped with a short-cap, screw-vial closure (cat.# 24495).

Notes

Some compounds traditionally analyzed by LC were not GC amenable and/or only fragments were detected. These compounds, and the mixes that contain them, are:
Abamectin (32586)
(E)-Fenpyroximate (32586)
Spinosad (32586)
Aldicarb (32588)
Hexythiazox (32588)
Thiacloprid (32588)
Clofentezine (32589)
Daminozide (32589)
