Scope

1.1 This procedure covers the determination of thiodiglycol (TDG) in surface water by direct injection using liquid chromatography (LC) and detected with tandem mass spectrometry (MS/MS). TDG is qualitatively and quantitatively determined by this test method. This test method adheres to single reaction monitoring (SRM) mass spectrometry. 1.2 This test method has been developed by U.S. EPA Region 5 Chicago Regional Laboratory (CRL). 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 The detection verification level (DVL) and reporting range for TDG are listed in Table 1. 1.4.1 The 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 ratio at the DVL. 1.4.2 The RL is the concentration of the Level 1 calibration standard as shown in Table 2. The reporting limit for this test method is 100 µg/L. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
