安捷伦7890B使用401脱氧柱

安捷伦7890B使用401脱氧柱 详细信息：

型号：401脱氧柱

规格：3m*Φ3

使用温度：280°C

编号：20221008001

应用：工业氢中氧氩氮的测定

GB/T 14605-93《氧气中微量氩、 氮和氪的测定气相色谱法》

氧和氩的物理性质相近，在色谱柱上较难分离，得到的色谱峰通常是一混合组分，而无 法定量，因此氧氩分离成为色谱分离中一大的难题。在国标GB/T 14605-93《氧气中微量氩、 氮和氪的测定气相色谱法》中是采用脱氧柱(401脱氧剂)先将氧脱除，而后使被检ce组分氩、 氮和氪经色谱柱分离后进入检ce器，达到测定分析氩、氮等组分的目的。

Details of 401 deoxidation column used by Agilent 7890B:

Model: 401 deoxidation column

Specification: 3m* Φ three

Operating temperature: 280 ° C

No.: 20221008001

Application: determination of oxygen, argon and nitrogen in industrial hydrogen

GB/T 14605-93 Determination of Trace Argon, Nitrogen and Krypton in Oxygen Gas Chromatography

The physical properties of oxygen and argon are similar, which is difficult to separate on the chromatographic column. The chromatographic peak obtained is usually a mixed component, which cannot be quantified. Therefore, the separation of oxygen and argon has become a major problem in chromatographic separation. In the national standard GB/T 14605-93 Determination of Trace Amounts of Argon, Nitrogen and Krypton in Oxygen Gas Chromatography, the deoxidizing column (401 deoxidizer) is used to remove oxygen first, and then the detected components of argon, nitrogen and krypton are separated by the chromatographic column before entering the detector, so as to achieve the purpose of determining and analyzing argon, nitrogen and other components.
