如何确定色谱分析条件(气相色谱和液相色谱)? 一般根据你分析样品的性质,确定分析条件,不同样品选择不同的参数,分析标准上都有分析条件,楼主可以查阅 ... 1、the purity of methyl lactate was analyzed by varian cp-3800 gas chromatography (gc) equipped with an ac-10 column, 30 m 3 0.32 mm 3 0.5 mm (oven temperature 250c, fid detector temperature 250c, vaporizer temperature 250c). methanol was as the solvent, toluene was used as internal standard. 最后一句含义是什么的呢, 2、 sample analysis. the liquid and vapor phases were analyzed using a hewlett-packard gc (model 6890) equipped with a flame ionization detector (fid). the gc column was a 25 m 0.5 ím bonded phase fused silica, ffap, capillary column. the injector and detector were at 453 k and 523 k, respectively. the oven was operated at variable, programmed temperature, from 428 k (where it was kept for 2 min) to 553 k at a rate of 30 kamin-1. helium (38 mlamin-1), 99.999% pure, was used as the carrier gas. concentration measurements were accurate to (0.0005 mole fraction. 这个的色谱条件 :1 色谱柱:柱商品名称,填料商品名称, 色谱 柱长度( cm )和内径( mm ),填料粒经( um ) 2.流动相:流动相组成和比例,流速(ml/min) :3.检测器:型号及参数(如波长nm) 4. 进样量:体积( ul ) 5 柱 温:(℃) 分别是什么, 查看更多
