氧气中微量氩、氮和氪的气相色谱
氧气中微量氩、氮和氪的气相色谱 详细信息：

名称：401脱氧柱
规格：2m*4mm
材质：玻璃柱或不锈钢
粒度：400-800um
应用：GB/T 14605-1993 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，而后使被检测组分氩、 氮和氪经色谱柱分离后进入检测器，达到测定分析氩、氮等组分的目的，但存在401脱氧剂 容易失效、且再生时操作复杂、耗时长等不足；在工业氧的测定分析中，现使用国标GB/T 3863-1995《工业氧的测定分析法》中采用的是铜氨溶液吸收氧，根据吸收后残气体积，计算 氧的含量，但存在分析操作复杂、准确性差、不适合大空分装置液氧中氧气浓度测定等问题。

为了克服现有的国标GB / T 14605-93《氧气中微量氩、氮和氪的测定气相色谱法》中401 脱氧剂容易失效、且再生时操作复杂、耗时长等不足，浩瀚色谱（山东）应用技术开发有限公司研发新型提供了一种快速、无需再 生、操作简单、完全脱除气体中氧的脱氧器；同时也解决了现有的国标GB/T 3863-1995《工 业氧的测定分析法》分析操作复杂、准确性差、不适合大空分装置液氧中氧气浓度测定等问 题，新型提供一种与普通型的气相色谱仪(TCD)联用，快速、准确、简便的测定大空分 装置液氧中氧气浓度的分析方法。

Gas Chromatography of Trace Argon, Nitrogen and Krypton in Oxygen
Gas Chromatography of Trace Argon, Nitrogen and Krypton in Oxygen Details:

Name: 401 Deoxygenation Column
Specification: 2m*4mm
Material: glass column or stainless steel
Granularity: 400-800um
Application: GB/T 14605-1993 Determination of trace argon, nitrogen and krypton in oxygen gas chromatography

The physical properties of oxygen and argon are similar, and it is difficult to separate on a chromatographic column. The chromatographic peak obtained is usually a mixed component and cannot be quantified. Therefore, the separation of oxygen and argon becomes a major problem in chromatographic separation. In the national standard GB/T 14605-93 "Determination of Trace Argon, Nitrogen and Krypton in Oxygen by Gas Chromatography", a deoxidizing column (401 deoxidizer) is used to remove the oxygen first, and then to make the detected components argon, nitrogen and krypton After being separated by the chromatographic column, it enters the detector to achieve the purpose of determining and analyzing argon, nitrogen and other components. However, 401 deoxidizer is prone to failure, complex operation during regeneration, and time-consuming; it is now used in the determination and analysis of industrial oxygen The national standard GB/T 3863-1995 "Industrial Oxygen Determination and Analysis Method" adopts copper ammonia solution to absorb oxygen. According to the residual gas volume after absorption, the oxygen content is calculated, but the analysis operation is complicated, the accuracy is poor, and it is not suitable for large air separation. The measurement of the oxygen concentration in the liquid oxygen of the device and other issues.

In order to overcome the shortcomings of the existing national standard GB/T 14605-93 "Determination of Trace Argon, Nitrogen and Krypton in Oxygen by Gas Chromatography", the 401 deoxidizer is prone to failure, complex operations during regeneration and time-consuming, etc. Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a new type of deaerator that is fast, does not require regeneration, is simple to operate, and completely removes oxygen from the gas; it also solves the existing national standard GB/T 3863-1995 "Industrial Oxygen Determination and Analysis Method" 》The analysis operation is complicated, the accuracy is poor, and it is not suitable for the determination of the oxygen concentration in the liquid oxygen of the large air separation unit. The new type provides a combination with the ordinary gas chromatograph (TCD) to quickly, accurately and easily determine the liquid of the large air separation unit. Analysis method of oxygen concentration in oxygen.
