问题的提出：
利用实验室定型的安捷伦，岛津，赛默飞，瓦里安，布鲁克等气相色谱仪测定工业氢中氧氩，氮的含量。
传统的解决方法：
依据GB/T3634.1—2006工业氢中氧，氩，氮的分离的方案，进行二维升级改造（进样阀+切换阀+401脱氧柱+13x分子筛柱），两次进样，差减法计算氧的含量。
传统方法的缺点：改装仪器，价格高，费时费力，效率低，不能满足生产快速检测的需要，使用受限。
浩瀚色谱（山东）应用技术开发有限公司，在不改造岛津安捷伦，赛默飞，瓦里安，布鲁克，PE等气相色谱仪的基础上，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：
岛津GC-14C，GC-2010，GC-2014，GC-2018,gc-2030
安捷伦6890,7890,8860,8890,7820,4890,5890,6820
赛默飞，瓦里安，布鲁克，PE
北分瑞利，东西电子，福立，华爱，科创，川仪，捷岛等国产仪器
名称：氧氩氮专用柱
型号：HH-O2ARN2
应用：GB/T3634.1—2006工业氢中氧，氩，氮的分离
Question raising:
Using laboratory standardized gas chromatographs such as Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, etc. to determine the content of oxygen, argon, and nitrogen in industrial hydrogen.
Traditional solutions:
According to the separation scheme of oxygen, argon, and nitrogen in industrial hydrogen according to GB/T3634.1-2006, a two-dimensional upgrade transformation was carried out (injection valve+switching valve+401 deoxygenation column+13x molecular sieve column), with two injections and differential calculation of oxygen content.
The disadvantages of traditional methods include high cost, time-consuming and labor-intensive modification of instruments, low efficiency, inability to meet the needs of rapid production testing, and limited use.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the HH-O2ARN2 oxygen argon nitrogen special packed column without modifying gas chromatographs such as Shimazu Agilent, Thermo Fisher, Varian, Brooke, PE, etc. The upgrade can be completed to determine the content of oxygen, oxygen, and nitrogen in industrial hydrogen with high efficiency and achieve interconnection.
