1.1 This test method covers sampling and analysis of liquid chlorine for the determination of oxygen (200 to 400 ppm), nitrogen (400 to 800 ppm), and carbon dioxide (800 to 1000 ppm) content at levels normally seen in liquid chlorine. Hydrogen and carbon monoxide concentrations in liquid chlorine are typically at or below the detection limit of this test method.
Note 1-The minimum detection limit of hydrogen using a 1 cm gas sample and argon carrier gas is 100 to 200 ppm. The detection limit for the other components is significantly lower.1.2 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. Specific hazards statements are given in Section 7.
1.3 Review the current Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.
