ASTM E2469 : 16

Standard Test Method for Chloride in Mono-, Di- and Tri-ethylene Glycol by Ion Chromatography

Standard Details

1.1 This test method covers the determination of inorganic chloride (chloride ion) in monoethylene glycol (MEG), diethylene glycol (DEG) and triethylene glycol (TEG) in the range of 0.01 to 1.0 mg/kg by ion chromatography (IC).

1.2 Ethylene glycol can be analyzed directly by this test method without any sample preparation or diluted with high quality deionized water if an autosampler is used and dilution is necessary (that is, 50:50 or other suitable ratio).

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3.1 The exception is the additional information of (psi) in 9.3.3, 11.1.1, and 11.2.1.

1.4 Review the current Safety Data Sheets (SDS) for detailed information concerning toxicity, first-aid procedures and safety precautions.

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 to determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 9.
