六六六丙体的分析,我们曾经对减差法及分配色层分析法作比较试验,证明色层分析较为适用。这个分配色层分析法,设备简单,操作时间虽比极谱分析法较长,但几个样品可同时进行分析,因此仍大大节省时间,故特作简单介绍,供大家参考。选择一种对六六六具有高度溶解力的溶剂—硝基甲烷,于吸着剂—硅胶上作为固定液相,随后使六六六样品溶解,加于固定液相中。然后选择一种与固定液相不相溶(或极微)的淋洗剂(石油醚的硝基甲烷饱和溶液)从固定液相中通过,利用六六六各异构体在硝基甲烷及淋洗剂间 BHC analysis, we have compared the subtraction method and the distribution of color analysis for comparative tests to prove that the color analysis is more applicable. The distribution of chromatography, the device is simple, although the operating time longer than the polarographic analysis, but several samples can be analyzed at the same time, it is still a big time-saving, it is for a brief introduction for your reference. Choose a solvent that has high solvency for HCH, nitromethane, on the sorbent-silica gel as the stationary phase, then dissolve the HCH sample and add it to the stationary phase. Then choose a fixed liquid phase immiscible (or minimal) rinse (petroleum ether, nitromethane saturated solution) from the stationary phase through the use of hexacosanoic isomers of nitromethane and Rinse room
