浩瀚GBT 3634.1-2006 工业氢中氧，氩，氮测定专用填充柱HH-O2AR

工业氢气中氧，氩的测定采用的是2次进样色谱法：
di1次进样测定氧+氩的总和；
第二次进样通过401脱氧柱，脱除氧，测定氩的含量；
两次差减，即可得出氧的含量。
此法操作复杂，需要2根色谱柱（1根脱氧柱），阀切换，两次进样，费时费力，无法满足工业快速检测的需要。

浩瀚色谱（山东）应用技术开发有限公司，与时俱进，研制出1根专用填充柱HH-O2AR，直接进样，即可测定氧，氩，氮的含量，柱效高，分离好，效率高，是浩瀚色谱，独树一帜的产品。

应用：GBT 3634.1-2006 氢气 第1部分 工业氢
Oxygen and argon in industrial hydrogen were determined by 2-injection chromatography:
Determination of the sum of oxygen + argon in the first injection;
The second injection passed through a 401 deoxygenation column to remove oxygen and determine the argon content;
The oxygen content can be obtained by subtracting the difference twice.
This method is complicated to operate, requires two chromatographic columns (one deoxygenation column), valve switching, and two injections, which is time-consuming and labor-intensive, and cannot meet the needs of rapid industrial detection.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times and has developed a special packed column HH-O2AR, which can be directly injected to measure the content of oxygen, argon and nitrogen. The column has high efficiency, good separation and high efficiency. High, is a vast spectrum, a unique product.
