The simultaneous separation and determination of a mixture of hydrocarbons and organochlorine compounds was successfully carried out by using sorption chromatography on a two-step microcolumn of silica and aluminium oxide for their fractionation, and a dual detector system. In addition to the separation and identification of hydrocarbons and heterocompounds containing nitrogen, oxygen and sulphur atoms, separation and identification of chlorinated hydrocarbons (dichlorobenzenes, p-chlorotoluene, hexachlorobutadiene, 1,2,4-trichlorobenzene and 2-chloronaphthalene), pesticides (chlorpicrin, aldrin, lindane, alpha- and beta-benzene hexachloride (BHC), endrin, dieldrin, endosulphan, methoxychlor) and herbicides (propanil, dichlobenil, trifluralin, difolatan) were achieved in mixtures containing polychlorinated biphenyl, strobane and chlordane.
通过在硅胶和氧化铝两步微柱上进行吸附色谱法对烃类和有机氯化合物混合物进行分馏，并采用双检测器系统，成功实现了烃类和有机氯化合物混合物的同时分离和测定。除了分离和鉴定烃类以及含氮、氧和硫原子的杂化合物外，还在含有多氯联苯、毒杀芬和氯丹的混合物中实现了氯代烃（二氯苯、对氯甲苯、六氯丁二烯、1,2,4 - 三氯苯和2 - 氯萘）、农药（氯化苦、艾氏剂、林丹、α - 和β - 六六六、异狄氏剂、狄氏剂、硫丹、甲氧滴滴涕）和除草剂（敌稗、二氯苯腈、氟乐灵、敌菌丹）的分离和鉴定。
