MS-5 ? 填充柱測定氮氣發(fā)生器中氧

，采用氣相色譜熱導(dǎo)法和氣相色譜氧化鋯法兩種方法,分別測試氮氣發(fā)生器所生成的氮氣樣品,通過比較兩種測量方法原理,氣相色譜氧化鋯法能夠有效去除這種氮氣樣品中氬氣的干擾,適合準(zhǔn)確定量氮氣發(fā)生器生成氮氣中的氧含量。

Determination of oxygen in a nitrogen generator by MS packed column Details:

At present, the nitrogen and high-purity nitrogen sources used for the gas chromatograph are all high-pressure nitrogen cylinders. To date, no high-purity nitrogen gas has been found to replace the cylinder.
High-purity nitrogen electrolysis unit. It is another new gas source generator for use with gas chromatographs.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. uses gas chromatography thermal conductivity method and gas chromatography zirconia method to test the nitrogen sample generated by nitrogen generator separately. By comparing the two measurement methods, gas chromatography zirconia method It can effectively remove the interference of argon in this nitrogen sample, and is more suitable for accurately quantifying the oxygen content in the nitrogen generator to generate nitrogen.
