Application Summary AI generated
This standard specifies the method for determining the purity and trace impurity components in high-purity gases, such as hydrogen, nitrogen, argon, and helium, using a gas chromatograph equipped with a helium ionization detector (HID). It is applied in the chemical industry, electronics manufacturing, and gas production facilities where ultra-high-purity gases are required, ensuring quality control for semiconductor fabrication and specialty gas analysis. The standard defines testing conditions, calibration procedures, and calculation methods to achieve accurate detection of impurities at parts-per-billion (ppb) levels.
