GB/T 28124-2025 《Gas analysis—Determination of the trace contents of hydrogen,oxygen,methane and carbon monoxide in inert gases—Gas chromatography with zirconia Detector》 Related products

GB/T 28124-2025 is a special project standard in the field of Gas Analysis, which specializes in the determination of trace hydrogen, oxygen, methane and carbon monoxide in inert gases, using zirconia Gas chromatography, CG. The standard specifies the test principle, instrument requirements, operation steps and result calculation methods, and is suitable for the detection of trace impurities in this type of inert gas. The standard can unify the detection method and ensure the accuracy of the data, providing a reliable technical basis for the purity control of inert gases in the fields of chemical industry, electronics, etc., production process optimization and scientific research experiment quality control.
