Popis:	A Finnigan 4500 mass spectrometer was modified to perform direct liquid introduction high-performance liquid chromatography—mass spectrometry (DLI-HPLCMS). The HPLCMS analysis of some 25 pesticides, including carbamates, chlorinated carboxylic acids and methyl ureas is described. The qualitative appearance of the spectra as well as detection limits are presented for both positive and negative ion detection. In most cases DLI-HPLCMS, using an 1:100 split, provided molecular weight information with sub-microgram detection limits and greatly increased specificity over HPLC detection.
