1.1This procedure covers the determination of aldicarb, carbofuran, oxamyl and methomyl (referred to collectively as carbamates in this test method) in surface water by direct injection using liquid chromatography (LC) and detected with tandem mass spectrometry (MS/MS). These analytes are qualitatively and quantitatively determined by this method. This method adheres to multiple reaction monitoring (MRM) mass spectrometry.
1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4The Detection Verification Level (DVL) and Reporting Range for the carbamates are listed in Table 1.
1.4.1The DVL is required to be at a concentration at least 3 times below the Reporting Limit (RL) and have a signal/noise ratio greater than 3:1. Fig. 1 displays the signal/noise ratios of the primary single reaction monitoring (SRM) transitions and Fig. 2 displays the confirmatory SRM transitions at the DVLs for the carbamates.
1.4.2The reporting limit is the concentration of the Level 1 calibration standard as shown in Table 2 for the carbamates.
