PURPOSE: To determine the saturated components, unsaturated components and aromatic components of hydrocarbon compounds rapidly and easily with good reproducibity with a high-speed liquid chromatography by using the specific 1st and 2nd columns which are connected in series.
CONSTITUTION: The 1st column in which the fully porous silica packing of about 80W100 fine-pore distribution, about 4W40μ grain sizes and about 380W570m2/g specific surface area (for example, formed by griding the gel obtained by treating a sodium silicate soln. with a mineral acid) is packed, and the 2nd column in which the silver-contg. silica packing prepd. by carrying about 0.05W20wt% silver in the above-mentioned silica packing are used by being conneced in series. More specifically, an org. chlorine solvent (may be mixed with a hydrocarbon solvent) is used as eluate, and the elute from the 2nd column is introduced into infrared ray detectors of about 5W50μl cell capacities, whereby the components of the hydrocarbon compounds are determined. It is desirable to make combination use of ultraviolet detectors for detection of aromatic components.
