- Scope
- This standard specifies the gas chromatographic method for the determination of trace amounts of hydrogen in gases. This standard is applicable to the determination of trace amounts of hydrogen in gases such as nitrogen, argon, oxygen, air, krypton, xenon, and argon for light bulbs, and is also applicable to fields such as medicine and electric power. The measuring range is 0.02～100×10-6 (volume fraction). When the sample to be tested contains more than 200×10-6 (volume fraction) of neon or more than 1000×10-6 (volume fraction) of helium, it will interfere with the determination of hydrogen. At this time, hydrogen, helium and neon need to be separated before this standard can be applied.
