Abstract

PURPOSE:To prevent the deterioration of a column and detection obstruction caused by unnecessary components, by a method wherein a specimen is coarsely separated by liquid chromatography to collect only an objective component which is, in turn, subjected to gas charomatography. CONSTITUTION:A specimen is coarsely separated in the column 4 of liquid chromatography and the eluted liquid corresponding to a fraction each containing an objective component is received by a specimen dish 26 while the eluted liquid corresponding to a fraction containing unnecessary components is received by a specimen dish 25. The former eluted liquid is concentrated in a concentrator 7 and a specimen boat 24 is moved by a magnet 27 so as to position the specimen dish 26 in an evaporation chamber 8. Only the objective component is evaporated under heating in the evaporation chamber 8 to be introduced into a capillary column 14 along with carrier gas. When the capillary column 14 is heated in a column over 19, the objective component is highly separated to be clearly detected by a detector 15 for gas chromatograph.
