GB/T 5831-2011
ActiveDetermination of trace oxygen in the gases - Colorimetric method
气体中微量氧的测定 比色法
Application Summary AI generated
This standard specifies a colorimetric method for determining trace amounts of oxygen in industrial gases, such as nitrogen, argon, and hydrogen. It is applied in chemical manufacturing, gas purification, and quality control laboratories where precise measurement of oxygen contamination at parts-per-million (ppm) levels is critical. The method is used to verify gas purity for applications like semiconductor production, welding atmospheres, and specialty gas handling.
