5A填充柱测定合成氨工艺气组分

5A填充柱测定合成氨工艺气组分 详细信息:


名称:填充柱
固定相:分子筛
规格:2m*3mm
型号:5A
应用:合成氨中永jiu气体测定


合成氨生产过程中的工艺物料都是以气体状态存在,对其检测方法多数是气相色谱法、热导-外标峰高定量法。气相色谱检测峰高定量法操作简单,仪器稳定性好,灵敏度适中,但对待测各种组分含量有一定范围要求。当含量超过一定范围时,峰高与含量就不成正比关系,即超线性,超线性的对应措施有稀释法及多个标准气分段标定法等,浩瀚色谱(山东)应用技术开发有限公司经过 摸索实践,采用一个标准气也能满足超线性的要求,从而减少标准气消耗,缩短分析时间,提高工作效率。

Determination of Synthetic Ammonia Process Gas Components by 5A Packed Column


5A Packed Column Determination of Synthetic Ammonia Process Gas Components Details:



Name: Packed Column

Stationary Phase: Molecular Sieve

Specifications: 2m*3mm

Model: 5A

Application: Permanent Gas Determination in Synthetic Ammonia


The process materials in the synthetic ammonia production process all exist in gaseous state, and most of the detection methods are gas chromatography, thermal conductivity-external standard peak height quantitative method. Gas chromatography detection peak height quantitative method is simple in operation, good in instrument stability and moderate in sensitivity, but there are certain requirements for the content of various components to be measured. When the content exceeds a certain range, the peak height is not proportional to the content, that is, super-linearity. The corresponding measures for super-linearity include dilution method and multiple standard gas segmentation calibration methods. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. Through exploration and practice, the use of a standard gas can also meet the requirements of super linearity, thereby reducing the consumption of standard gas, shortening the analysis time, and improving work efficiency.
