摘要： A combination of a liquid chromatograph and a gas chromatograph was a possible measure for improving precision in analyzing organic chemical substances. However, because elutes from liquid chromatoghaphies contain water and a highly polar solvent, injection thereof into a gas chromatograph has been impossible. Consequently, to develop an analytical method which realizes that combination and an apparatus thereof has been a subject. The method of the quantitative analysis comprises subjecting a sample for analysis prepared beforehand by extracting organic chemical substances from an assay sample to fractionation by a liquid chromatograph, continuously adsorbing a fractionated elute containing a substance to be determined onto a solid-phase cartridge while conducting the fractionation, eluting this substance, which has been adsorbed on the solid-phase cartridge, with an eluent, and transferring the elute to a storage chamber of a gas chromatograph.

摘要： This invention relates to an analytical method and an apparatus utilizing a SPE cartridge, which can realize enhanced accuracy and workability in the analysis of trace substances, such as residual pesticides, can clean the inside of piping, needle valves etc, can eliminate the influence on the analysis and can conduct these operations automatically. In the analytical method and apparatus utilizing a SPE cartridge, analytes previously adsorbed to a SPE cartridge is eluted with a solvent from a liquid feed pump. The eluate was injected into a storage chamber in a gas chromatograph through a needle inserted into an injection port in the storage chamber. The needle is pulled up from the injection port, and the inside of the needle is washed with a solvent fed from the liquid feed pump. The wash liquid is discarded, and the analysis of organic compounds as analytes in an subject sample is carried out.
