Method 536: Determination of Triazine Pesticides and Their Degradates in Drinking Water by Liquid Chromatography Electrospray Ionization Tandem Mass Spectrometry (LC/ESI-MS/MS). Version 1.0.

摘要

This is a liquid chromatography electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS) method for the determination of triazine pesticides and their degradation products in finished drinking waters. This method requires the use of MS/MS in Multiple Reaction Monitoring (MRM) mode to enhance selectivity. Precision and accuracy data have been generated for the detection of the triazine pesticides and their degradates in reagent water and finished drinking water from both groundwater and surface water sources. The single laboratory Lowest Concentration Minimum Reporting Level (LCMRL) has also been determined in reagent water.
