On-line solid-phase extraction-gas chromatographyion-trap tandem mass spectrometry
(SPE-GC-MS/MS) has been used for the trace-level determination of polar and apolar …

An improved setup for interfacing solid‐phase extraction (SPE) and gas chromatography
(GC) was constructed. Its working mechanism resembles that of the loop‐type interface, but …

An improved set‐up for solid‐phase extraction with thermal desorption coupled on‐line to
gas chromatography (SPETD‐GC) is presented. It includes a newly designed liner for a …

atmospheric pressure chemical ionization (APCI) followed by (tandem) mass spectrometry …

A rapid multiresidue method for the analysis, at trace levels, of 96 target analytes in field
water samples has been developed. Pesticide parent compounds, from a variety of chemical …

A multi-residue method for the trace-level determination of 34 pesticides and various
transformation products was developed by using on-line solid-phase extraction and either …

A rapid and reproducible multi-residue analysis was developed for the simultaneous
determination of 46 pesticides belonging to triazines. organophosphorus and …

Publisher Summary This chapter presents the official methods of analysis of priority
pesticides in water using gas chromatographic techniques. The progress in incorporating …

The aim of this study is to propose an analytical method for determining different classes of
pesticides in water using LC–ESI-MS/MS. Two techniques of field-sampling and analyte …
