Detector	Shimadzu 8045 MS/MS
Ion Source:	Electrospray
Ion Mode:	ESI+/ESI-
Mode:	Scheduled MRM
Instrument	Shimadzu Nexera X2
Sample Preparation	A 1 ppm stock sample was prepared by adding 1.67 µL of each standard to 990 µL of acetonitrile in a 2.0 mL amber, short-cap vial (cat.# 21142) capped with a 9 mm short cap (cat.# 24497). The sample was briefly vortexed. A 50 µL aliquot was further diluted into 950 µL of acetonitrile.
Notes	Some compounds traditionally analyzed by GC were not LC amenable. These compounds, and the mixes that contain them, are: Chlorgenapyr (32587) Cyflurthrin (32590) Pyridaben (32588) Methyl parathion (32591)
