Gas-liquid two-phase flow chromatography analyzer and analysis method using the device

摘要

The present invention is a chromatographic analytical device and a detection unit and the accommodating portion and its separation column stationary phase comprising a polymer material and the sample injection section and the introduction of the carrier gas is the main mobile phase medium is coated There is provided between sample injection part of the separation column inlet and the carrier gas inlet, and has a solvent introducing means for adding and mixing a liquid solvent as the second mobile phase medium carrier gas, the carrier gas introduction amount In those with a temperature control mechanism of the flow path control mechanism and each part of the solvent added amount, the liquid film thickness and the inner diameter capillary column partially occluded liquid plugs forming a plurality of spaced apart in the longitudinal direction of the column the gas-liquid two to move the column outlet direction mobile phase medium in a state of vapor-liquid phase alternates intermittently, to separate the sample by using the distribution of the column stationary phase and the solvent liquid film mobile phase medium The present invention relates to chromatographic analysis method capable of chromatograph phase flow, and by using this apparatus, it is separated by a high pressure pump without the sample.
