工業(yè)氫氣分析項目執(zhí)行國家標準(GB/T3634.1—2006).其中氧、氬和氮含量的測定采用的是氣相色譜法,配備脫氧柱和切換柱兩次進樣,測定樣品氣中氬和氮的含量,用差減法計算出樣品.此方法人為地兩次手動進樣,每次分析樣品在六通閥的定量管中由于受溫度壓力不同給分析結(jié)果帶來人為誤差.
?
為解決現(xiàn)有氣相色譜法在對氧氣、氬氣、氮氣等氣體通過色譜柱進行分析測定時存在色譜柱老化后氧氬峰和氮氣峰分離度降低無法進行氣體測定及工藝不穩(wěn)定操作下脫氧柱有效利用率低的缺陷。

The industrial hydrogen analysis project follows the national standard (GB/T3634.1-2006). The determination of oxygen, argon, and nitrogen content is carried out using gas chromatography, equipped with a deoxygenation column and a switching column for two injections. The content of argon and nitrogen in the sample gas is determined, and the sample is calculated by subtraction This party has manually injected samples twice, and each time the sample is analyzed in the quantitative tube of the six way valve, the analysis results are subject to human error due to temperature and pressure differences
To address the shortcomings of existing gas chromatography methods in analyzing and determining gases such as oxygen, argon, and nitrogen through chromatographic columns, such as decreased separation of oxygen argon and nitrogen peaks due to column aging, inability to perform gas determination, and low effective utilization of deoxygenation columns under unstable process operation.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a dedicated packed column for the determination of oxygen and argon in hydrogen, addressing the shortcomings of the national standard, such as two valves, two injections, and short lifespan of the 401 deoxygenation column. The analysis time is short, with one analysis completed in 3 minutes. The oxygen and argon separation is high, the peak shape is symmetrical, and the efficiency is high.
