ASTM E1746 – Standard Test Method for Sampling and Analysis of Liquid Chlorine for Gaseous Impurities

1.1 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.
