GB/T 17873-1999 Pure Neon
This standard has been replaced by GB/T 17873-2014
This standard specifies the requirements, testing methods, packaging, labeling, storage, and transportation of pure neon products.
This standard is applicable to neon produced by air separation method, which is mainly used for electric light sources, infrared remote sensing, and scientific research.
Determination of oxygen, hydrogen (calculated as oxygen), and nitrogen:
4.3.1 Method: Use a gas chromatograph equipped with a helium ionization detector to determine oxygen, hydrogen (as oxygen), and nitrogen in neon.
4.3.2 Instrument Parameters
4.3.2.1 Detection limit: Oxygen: 0.5 x1 0-6-, (v/v), Nitrogen: 0.5 x1 0-6 (v/v),
4.3-2.2 Chromatographic Column: Use a particle size of for chromatographic analysis. 0.25-0.40mm 0.5nm (5 angstroms) molecular sieve with an inner diameter of 4m and a length of approximately
Activate a 3m stainless steel tube with dry helium gas at 300 ℃ for 6 hours, or use other equivalent chromatographic columns.
4.1 2.3 Carrier gas: High purity helium gas at a rate of approximately 30m I./min, purified to a impurity content approximately one quantity lower than that of the tested component
Grade.
4.3. 2.4 Doping gas: about 0.05 MPa; High purity hydrogen with a flow rate of 5-10m L/min.
4.3.2.5 Sample volume: approximately 3 mL,
4.3-2.6 Temperature: The detector and chromatographic column box are both at room temperature.
