气相色谱仪汽化室出口一般适用于连接不锈钢填充柱。当用聚四氟乙烯柱时,通常是在聚四氟乙烯柱头内插一根Φ2×0.5×20mm不锈钢管,柱头外套一个Φ14×6mm硅橡胶垫圈,再用M14螺帽固定。但是这种方法不够稳固,柱子容易脱落。特别是用ECD分析高沸点化合物时,柱温在200℃左右,柱前压高达3～4kg/cm~2,即使经常更新硅橡胶垫,柱头也容
Gas chromatograph vaporization chamber outlet is generally suitable for connecting stainless steel packed column. When using Teflon column, it is common to insert a Φ2 × 0.5 × 20mm stainless steel tube into the Teflon column stiffener and a Φ14 × 6mm silicone rubber gasket on the stigma jacket, then use M14 nut to fix it. However, this method is not stable enough, easy to fall off the column. Especially when using ECD to analyze high-boiling compounds, the column temperature is about 200 ℃ and the column pressure is up to 3 ~ 4kg / cm ~ 2. Even if the silicone rubber pad is often updated,
