A robust multi-residue method for the monitoring of 25 endocrine disruptors at ultra-trace levels in surface waters by SPE-LC-MS/MS

Abstract

Analysis of surface water samples with solid phase extraction and tandem mass spectrometry with dansyl chloride derivatization enables the environmental monitoring of 25 endocrine disruptors at ultra-trace levels.

Solid phase extraction technology combined with UPLC-MS/MS: a method for detecting 20 β-lactamase antibiotics traces in goat's milk

“…29 The combination of the advantages of high separation, speed and high sensitivity, and large sample ux of high-performance liquid chromatography with a fast-scanning mass spectrometer greatly shortens the analysis time and improves the sensitivity of mass spectrometry detection. 30 It is widely used in food analysis, 31,32 environmental analysis 33,34 and detection of other complex matrix residues. [35][36][37] These extraction-based pre-treatment methods have been considerably successful; however, they use large amounts of consumables and are expensive to operate.…”
