Screening for Pyrethroid Insecticides in Sediment Samples by GC-MS/MS
23 Apr 2012A simple screening method for pyrethroid insecticides in sediment samples is described in this application note. Electron impact ionization (EI) with tandem MS/MS in combination with programmed temperature vaporization injection (PTV) were used in order to obtain excellent specificity and low limits of detection of pyrethroids in river and lake sediments.

GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.
