Liquid chromatography–mass spectrometry (LC-MS)
Determination of 208 pesticide residues and their metabolites in foods using Oasis PRiME HLB and Xevo TQ-GC
10 December 2018 | By Waters
Gas chromatography-mass spectrometry (GC-MS) has been a common analytical method for pesticide measurement due to its high efficiency of separation, along with its qualitative and quantitative performance.
A robust and sensitive method for the direct analysis of polar pesticides in food and environmental samples without derivatisation
6 December 2018 | By Sciex
This application note discusses how some polar compounds are not amenable to the extraction procedure. It discusses how chromatographic methods or poor ionisers require additional single-residue methods which involve time-consuming preparation and separation, and often involve derivatisation to improve detection.
