国内使用日本YEW8110型工业气相色谱仪的企业较多。下面就该仪器应用维修技术、常见故障分析如下。一、载气等气体的净化载气和燃气氢气、助燃气Air一般都要进行净化。对这些气体纯度的要求,主要取决于所用的鉴定器以及色谱柱填充物的特性和分析对象的要求。使用分子筛等吸附柱时,载气中的微量水分将影响色谱柱的活化、寿命和分离效能。微量分析则要求载气的纯度较高。用氢火焰离子化鉴定器进行微
Domestic use of Japanese YEW8110-type industrial gas chromatography more companies. The following instrument maintenance technology, common fault analysis is as follows. First, the carrier gas and other gases to purify the carrier gas and gas hydrogen, gas-assisted Air generally have to be purified. The requirements for the purity of these gases depend primarily on the qualifier used, the characteristics of the column packing, and the requirements for the analyte. When using molecular sieve adsorption column, the carrier gas trace moisture will affect the activation of the column, life and separation efficiency. Trace analysis requires a higher purity of the carrier gas. Micro-hydrogen flame ionization detector
