工业氢气分析项目执行guo家标准(GB/T3634.1—2006).其中氧、氩和氮含量的测定采用的是气相色谱法,配备脱氧柱和切换柱两次进样,测定样品气中氩和氮的含量,用差减法计算出样品。

　　标准不足:

　　1.需要进样2次，费时费力，效率低下，分析时间长。

　　2.两次手动进样,每次分析样品在六通阀的定量管中由于受温度压力不同给分析结果带来人为误差

　　3.采用401脱氧柱，使用周期短，需经常更换，十分麻烦。

　　浩瀚色谱（山东）应用技术开发有限公司，采用新技术，研发新方案，一次进样即可完成氧，氩，氮的分离，效率高，分析时间短。脱氧剂寿命长。

　　The industrial hydrogen analysis project follows the national standard (GB/T3634.1-2006). The determination of oxygen, argon, and nitrogen content is carried out using gas chromatography, equipped with a deoxygenation column and a switching column for two injections. The argon and nitrogen content in the sample gas is measured, and the sample is calculated using subtraction method.

　　Insufficient standards:

　　1. Two injections are required, which is time-consuming and labor-intensive, with low efficiency and long analysis time.

　　2. Two manual injections, with each analysis of the sample in the quantitative tube of the six way valve causing human error in the analysis results due to different temperature and pressure

　　3. Adopting a 401 deoxygenation column has a short service cycle and requires frequent replacement, which is very troublesome.

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts new technologies and develops new solutions. The separation of oxygen, argon, and nitrogen can be completed in one injection, with high efficiency and short analysis time. Deoxidizer has a long lifespan.
