Comparison of Liquid and Gas Chromatographic Mass Spectrometry for the Determination of Multiclass Pesticides at Low Concentrations

Two identical triple quadrupole mass spectrometers, operated in the Selected Reaction Monitoring mode, under exactly the same parameters' settings, were employed for the comparison of GC-MS/MS and LC-MS/MS techniques in the analysis of 221 pesticides at low-concentration levels. The comparison was performed with the use of analytical standards' solutions that contained no matrix. The evaluated parameters for the comparison were the...
