GB/T 28124-2025 "Gas analysis—Determination of trace hydrogen, oxygen, methane, and carbon monoxide in inert gases—Zirconia gas chromatography" specifies a method for the determination of trace hydrogen, oxygen, methane, and carbon monoxide in inert gases such as helium, neon, argon, krypton, and xenon using gas chromatography with a zirconia detector. This method enables highly sensitive measurement of the aforementioned trace active impurities in inert gas matrices through a specific separation and detection system.
