GB/T3634.1—2006工业氢中氧，氩，氮的分离的分离需要采用二维色谱系统:1根5A分子筛柱，1根401脱氧柱，2个六通阀（1个进样，一个切换）。

　　实验室定型的气相色谱仪上改造，价格高昂，费时费力，效率低，一旦改造，仪器就变为专用的，原功能受到影响，仪器的使用效率下降，不实用。

　　浩瀚色谱（山东）应用技术开发有限公司，在不改造色谱仪器的基础上，研制HH-O2ARN2氧氩氮专用填充柱，即可完成升级，测定工业氢中氧，氧，氮的含量，效率高，实现互联互通。

　　适用于:赛默飞，瓦里安，布鲁克，PE，岛津，安捷伦进口仪器及北分瑞利，东西电子，华爱，川仪，科创，福立等国产仪器

　　The separation of oxygen, argon, and nitrogen in industrial hydrogen according to GB/T3634.1-2006 requires the use of a two-dimensional chromatography system: one 5A molecular sieve column, one 401 deoxygenation column, and two six way valves (one for injection and one for switching).

　　The modification of laboratory standardized gas chromatographs is expensive, time-consuming, and inefficient. Once modified, the instrument becomes specialized, affecting its original function and reducing its efficiency, making it impractical.

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the HH-O2ARN2 oxygen argon nitrogen special packed column without modifying the chromatographic instrument, which can be upgraded to measure the content of oxygen, oxygen, and nitrogen in industrial hydrogen with high efficiency and achieve interconnection.

　　Applicable to: imported instruments from Thermo Fisher, Varian, Brooke, PE, Shimadzu, Agilent, as well as domestic instruments such as Beifenruili, Dongxi Electronics, Huaai, Chuanyi, Sci Tech Innovation, and Fuli
