800mm*4mm玻璃球色谱柱
800mm*4mm玻璃球色谱柱目详细信息：

规格：0.8m*4mm

粒度：80目

填充物：玻璃球
二氧化碳中碳氢化合物项方法描述如下：“取本品作为供试品；取甲烷含量为0.0020%的气体（以氮气为稀释剂）作为对照气体，照气相色谱法(通则0521)试验，用玻璃球为填料的色谱柱（0.8mX4mm，8 0目）；柱温为110°C;进样口温度为110°C ; 检测器温度为120°C。量取供试品气体与对照气体，注入气相色谱仪，在净化温度为360°C时测得的峰面积为相应空白值；量取供试品气体与对照气体，注人气相色谱仪，测定峰面积，减去相应空白值后的峰面积为校正峰面积。按外标法以校正峰面积计算，含碳氢化合物。

The method of hydrocarbons in carbon dioxide is described as follows: "Take this product as a test product; take a gas with methane content of 0.0020% (using nitrogen as a diluent) as a control gas, and test according to gas chromatography (general rule 0521), using glass Chromatography column with balls as packing (0.8mX4mm, 80 mesh); column temperature is 110 ° C; inlet temperature is 110 ° C; detector temperature is 120 ° C. Measure the test gas and control gas and inject Gas chromatograph, the peak area measured at a purification temperature of 360 ° C is the corresponding blank value; the test gas and the control gas are measured, injected into the gas chromatograph, the peak area is measured, and the peak after subtracting the corresponding blank value The area is the corrected peak area. The calculated peak area is calculated by the external standard method and contains hydrocarbons.
