During regulatory analysis of pesticides and industrial chemicals, compounds are frequently
encountered which cannot be readily identified by gas chromatography alone on two or …

A method for detection, quantitation, and confirmation of more than 100 pesticides by gas
chromatography (GC) with ion trap mass spectrometry (MS/MS) has been developed. The …

The value of mass spectrometry as a means of qualitative analysis of unknown compounds
or for confirmation of the identity of suspected compounds is well recognized. Mass spectra …

By utilizing the information available from highresolution mass spectral data of pesticides, it
has been possible to identify ions in the spectra of each pesticide whose elemental …

This chapter describes recent advances in GC‐MS including chromatographic separations,
different mass analyzers hyphenated to GC, matrix effects in GC‐MS analysis and various …

A series of nitrogen-and phosphorus-containing pesticides (amines, anilides, carbamates,
phosphonates, phenylureas, sulfonylureas, and triazines) was examined by thermospray …

The use of gas chromatography-mass spectrometry (GC-MS) with electron impact (EI) and
positive and negative chemical ionization (PCI and NCI, respectively) is a valuable …

The analyses of synthetic pesticide residues in the presence of a multitude of naturally
occurring organic compounds found in plant or animal tissue presented analytical problems …

Several individual and multiresidue analytical methods are available for gas
chromatographic—mass spectrometric confirmation and identification of pesticide residues …

For efficiency in a regulatory setting, multiresidue methods (MRMs) are preferred to single-
residue methods (SRMs) for the analysis of pesticides in agricultural products, since many …
