This test method covers sampling and analysis of liquid chlorine for the determination of oxygen (200 to 400 μg/g), nitrogen (400 to 800 μg/g), 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 cm3 gas sample and argon carrier gas is 100 to 200 μg/g.2 The detection limit for the other components is significantly lower.

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

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

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.
