Scope

1.1 This test method covers the gas chromatographic determination of impurities in monoethylene glycol including 1,3dioxolane-2-methanol, diethylene glycol (DEG) and triethylene glycol (TEG). The purity of monoethylene glycol (MEG) is also calculated. A similar test method, using the internal standard calibration technique and the external standard calibration technique, is Test Method E2409. 1.2 This test method is applicable for monoethylene glycol purities of 98.0 mass % or higher. 1.3 The limit of detection (LOD) for 1,3-dioxolane-2methanol, DEG and TEG is 0.0002 mass %. 1.4 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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. 1.7 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.
