Examples of this type of herbicide are imazapyr, m-imazamethabenz, p-imazamethabenz, m,p-imazamethabenzmethyl, imazethapyr and imazaquin. Imazapyr has been determined at the xg/kg level in 0.1 M ammonium acetate extracts of soil by microwave-assisted extraction using electron capture negative chemical ionisation mass spectrometry [432]. High-performance liquid chromatography with UV detection at 250 nm has been used to determine imazapyr in methanol extracts of soil [433]. [Pg.127]

The objective of this study is to identify the major metabolites of the drug in question. For this study, the drug in question is incubated with an appropriate in vitro metabolic system to allow the formation of metabolites. Metabolites are then identified using analytical chemical approaches. The in vitro experimental system of choice is human hepatocytes, with high-performance liquid chromatography/mass spectrometry (HPLC/MS) or tandem mass spectrometry (HPLC/MS/MS) as the most convenient analytical tool to identify the metabolites.
