ABSTRACT:
A liquid chromatograph comprises an analyzing chip in which a capillary is formed in a substrate and a detector section is disposed downstream of the capillary. The capillary is covered so that an inlet opening end and an outlet opening end of said capillary flow path is opened. A frame member has a sample introduction path, a carrier liquid introduction path and a liquid discharge path. The analyzing chip is movably disposed in the frame member so that the inlet opening end and the outlet opening end of the capillary are selectively in communication with and/or under interruption against said sample introduction path, the carrier liquid introduction path and the liquid discharge path. The liquid chromatograph is very small in size but is easy to handle. Incidentally, there is disclosed also a sample introduction apparatus and method for the chromatograph, and an FET type detector suitable for the chromatograph.
