Sample Preparation

100 µL of each standard was combined with 200 µL acetonitrile (final volume 1 mL) for a final concentration of 10 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.
Canadian pesticide standards are also available as a kit: Canadian pesticides kit (cat.# 32592).
