Automated sample preparation with extraction columns followed by liquid chromatography-ionspray mass spectrometry interferences, determination and degradation of polar organophosphorus pesticides in water samples
TL;DR: In this paper, the determination of polar and/or thermally labile organophosphorus pesticides trichlorfon, dichlorvos, dimethoate, oxydemeton-methyl, mevinphos (cis and trans), demeton-S-methyl and fenamiphos, fenitrothion, fenthion and diazinon in water samples was investigated using solid-phase extraction followed by liquid chromatography-ionspray mass spectrometry (LC-ISP-MS).

Trace determination of herbicides in estuarine waters by liquid chromatography-high-flow pneumatically assisted electrospray mass spectrometry
TL;DR: High-flow pneumatically assisted electrospray was applied to the characterization of triazine, offering greater sensitivity for triazines than phenylurea herbicides, whereas the use of LC-ESP-MS offered an enhancement in sensitivity for phenylUREa herbicide.

Temperature and extraction voltage effect on fragmentation of organophosphorus pesticides in liquid chromatography–atmospheric pressure chemical ionization mass spectrometry
TL;DR: In this article, the effect of the probe temperature and extraction voltage on sensitivity and fragmentation of several organophosphorus pesticides was evaluated, and the optimum conditions with regard to best sensitivity and structural information were used to calculate the recoveries of the studied pesticides.

E. Benfenati,P. Grasso,C. Molina,Damià Barceló,C. Giarei,Silvana Galassi,L. Guzzella,G. Stella,I. Grabec Svegl,Božidar Ogorevc +9 more
TL;DR: An interlaboratory analysis of selected labile pesticides, chosen among priority compounds, indicated by a European Commission Report as lacking valid analytical procedures, finds that most of these compounds show stability problems both in solution and during analysis.
