haohan氧氩测定专用填充柱应用在安捷伦8890上HH-ARO2-III

氧氩的分离一直是一个难题，通常有以下方法：

1.多柱切割技术，配置复杂；
2.有液氮干冰低温冷阱方案，运行成本高昂
3.加长柱子/或者毛细管，柱温也要控制30度左右，温控太难
4.采用脱氧柱，两次进样，一次测氧氩合峰，1次脱氧后，测定氩，差减法得到氧含量，操作复杂，费时费力，定量误差大。

浩瀚色谱（山东）应用技术开发有限公司，研制的《氩氧分离专用填充色谱柱》，柱效高，O2，Ar分离好，峰型对称，分析时间短。即使在120度状态下，氧氩依旧可以分离。

型号：HH-ARO2-III

应用：氧，氩的分离

The separation of oxygen and argon has always been a difficult problem, and there are usually the following methods:
1. Multi column cutting technology with complex configuration;
2. There is a liquid nitrogen dry ice low-temperature cold trap solution, which has high operating costs
3. Extend the column/or capillary tube, and control the column temperature at around 30 degrees, as temperature control is too difficult
4. Using a deoxygenation column with two injections, measuring the oxygen argon peak once, and measuring the argon after one deoxygenation, the oxygen content can be obtained by subtraction method. The operation is complex, time-consuming, and labor-intensive, with large quantitative errors.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a special packed chromatography column for argon oxygen separation, which has high column efficiency, good separation of O2 and Ar, symmetrical peak shapes, and short analysis time. Even at 120 degrees, oxygen and argon can still be separated.
