ASTM E2787-21

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: E2787 − 11 (Reapproved 2016) E2787 − 21
Standard Test Method for
Determination of Thiodiglycol in Soil Using Pressurized
Fluid Extraction Followed by Single Reaction Monitoring
Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/
1
MS)
This standard is issued under the fixed designation E2787; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This procedure covers the determination of thiodiglycol (TDG) in soil using pressurized fluid extraction (PFE). A
2
commercially available PFE system wasis used, followed by analysis using liquid chromatography (LC), and detected with
tandem mass spectrometry (MS/MS). TDG is qualitatively and quantitatively determined by this method. This method adheres to
single reaction monitoring (SRM) mass spectrometry.
1.2 The Method Detection Limitmethod detection limit (MDL) and Reporting Rangereporting range for TDG are listed in Table
1.
1.2.1 The MDL is determined following the Code of Federal Regulations, 40 CFR Part 136, Appendix B.
1.2.2 The reporting limit (RL) is calculated from the concentration of the Level 1 calibration standard as shown in Table 4. The
RL for this method is 200 ppb. Reporting range concentrations are calculated from Table 4 concentrations assuming a 5 μL
injection of the lowest level calibration standard, 5 g sample, and a 2 mL final extract volume.
1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this
standard.
1.4 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, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
1.5 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.
