Scope

This document provides an explanation of the principle of using a zirconia detector gas chromatography to determine trace amounts of hydrogen, oxygen, methane, and carbon monoxide in inert gases, and specifies the test conditions, reagents and materials, instrumentation, samples, test procedures, test data processing, precision and measurement uncertainty, quality control and assurance, and requirements for test reports.
This document is applicable to the determination of trace amounts of hydrogen, oxygen, methane, and carbon monoxide in nitrogen, helium, neon, argon, krypton, and xenon. The measurement range is (005～20)×10-6 (mole fraction).
