工业氢中氧氧氮的测定国标中采用的是二维气相色谱法，5A分子筛+401脱氧柱的二次进样，操作复杂，费时费力。
在定型的气相色谱仪上改造，工程大，价格高，一旦改装，仪器原有的功能必定受到影响，仪器的效率降低。
浩瀚色谱（山东）应用技术开发有限公司，研究出2024新款氢中氧氩氮分离的专用填充柱，1根柱子即可完成氧，氩，氮的分离，结果表明方法简便、准确和快速。无需改造仪器即可完成升级，效率高，一机多用。
适用于：安捷伦6890,7820,7890,8890,8890,4890,5890,6820等各种型号的气相色谱仪
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
The national standard for the determination of oxygen, oxygen, and nitrogen in industrial hydrogen uses two-dimensional gas chromatography with a secondary injection of 5A molecular sieve and 401 deoxygenation column, which is complex and time-consuming.
The modification of a standardized gas chromatograph involves a large amount of engineering and high cost. Once modified, the original functions of the instrument will inevitably be affected, and the efficiency of the instrument will be reduced.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a special packed column for the separation of oxygen, argon, and nitrogen in hydrogen in 2024. One column can complete the separation of oxygen, argon, and nitrogen. The results show that the method is simple, accurate, and fast. Upgrade can be completed without the need for instrument modification, with high efficiency and multiple uses for one machine.
Applicable to various models of gas chromatographs such as Agilent 68907820789088908890489058906820
Name: Oxygen Argon Nitrogen Special Column
Model: HH-O2ARN2
Application: GB/T3634.1-2006 Separation of Oxygen, Argon, and Nitrogen in Industrial Hydrogen
