氧氣中微量氬、氮和氪的氣相色譜
氧氣中微量氬、氮和氪的氣相色譜 詳細(xì)信息：

名稱(chēng)：401脫氧柱
規(guī)格：2m*4mm
材質(zhì)：玻璃柱或不銹鋼
粒度：400-800um
應(yīng)用：GB/T 14605-1993 氧氣中微量氬、氮和氪的測(cè)定 氣相色譜法

氧和氬的物理性質(zhì)相近，在色譜柱上較難分離，得到的色譜峰通常是一混合組分，而無(wú) 法定量，因此氧氬分離成為色譜分離中一大的難題。在國(guó)標(biāo)GB/T 14605-93《氧氣中微量氬、 氮和氪的測(cè)定氣相色譜法》中是采用脫氧柱(401脫氧劑)先將氧脫除，而后使被檢測(cè)組分氬、 氮和氪經(jīng)色譜柱分離后進(jìn)入檢測(cè)器，達(dá)到測(cè)定分析氬、氮等組分的目的，但存在401脫氧劑 容易失效、且再生時(shí)操作復(fù)雜、耗時(shí)長(zhǎng)等不足；在工業(yè)氧的測(cè)定分析中，現(xiàn)使用國(guó)標(biāo)GB/T 3863-1995《工業(yè)氧的測(cè)定分析法》中采用的是銅氨溶液吸收氧，根據(jù)吸收后殘氣體積，計(jì)算 氧的含量，但存在分析操作復(fù)雜、準(zhǔn)確性差、不適合大空分裝置液氧中氧氣濃度測(cè)定等問(wèn)題。

為了克服現(xiàn)有的國(guó)標(biāo)GB / T 14605-93《氧氣中微量氬、氮和氪的測(cè)定氣相色譜法》中401 脫氧劑容易失效、且再生時(shí)操作復(fù)雜、耗時(shí)長(zhǎng)等不足，浩瀚色譜（山東）應(yīng)用技術(shù)開(kāi)發(fā)有限公司研發(fā)新型提供了一種快速、無(wú)需再 生、操作簡(jiǎn)單、完全脫除氣體中氧的脫氧器；同時(shí)也解決了現(xiàn)有的國(guó)標(biāo)GB/T 3863-1995《工 業(yè)氧的測(cè)定分析法》分析操作復(fù)雜、準(zhǔn)確性差、不適合大空分裝置液氧中氧氣濃度測(cè)定等問(wèn) 題，新型提供一種與普通型的氣相色譜儀(TCD)聯(lián)用，快速、準(zhǔn)確、簡(jiǎn)便的測(cè)定大空分 裝置液氧中氧氣濃度的分析方法。

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.
