摘要
This invention provides a chromatographic apparatus comprising an introduction part for a carrier gas as a main mobile phase medium, a sample injection part, a separation column comprising a stationary phase formed by coating a polymeric material, a part for housing the separation column, and a detector. The sample injection part is provided between the carrier gas introduction part and the inlet of the separation column. The chromatographic apparatus further comprises a solvent introduction means for adding a liquid solvent as a second mobile phase medium to a carrier gas and mixing them together, a mechanism for regulating the amount of the carrier gas introduced and the amount of the solvent added, and a mechanism for regulating the temperature of each flow passage. A plurality of clogging liquid stoppers, of which the liquid film thickness is equal to the inner diameter of a capillary column, are partly provided at predetermined intervals within the column in a longitudinal direction of the column. In such a state that a gas phase and a liquid phase are intermittently alternated, a mobile phase medium is moved toward a column outlet and a sample is separated by utilizing distribution between the solvent liquid film of the mobile phase medium and the column stationary phase. There is also provided a chromatographic analytical method utilizing this apparatus. According to this method, a sample can be separated without using any high pressure pump.
