CHROMATOGRAPH APPARATUS

PROBLEM TO BE SOLVED: To provide a small-sized chromatograph apparatus of high capacity. SOLUTION: The chromatograph apparatus of high capacity comprises an injection block 1 for injecting a sample fluid and a carrier fluid, plates A15 and B16 having grooves 21 provided to their surface and having fixing surfaces on the inner surfaces of the grooves 21, the gas separation part 2 arranged on the downstream side of the injection block 1 and forming a flow channel by stacking a plurality of the plates A15 and B16 and allowing the grooves 21 of the plates A15 and B16 to communicate with each other and the detection part 3 communicating with the outlet of the gas separation part 2. The gas separation part 2 is miniaturized and the respective compositions in a sample fluid are separated with high precision by the fixing phase provided in the sufficiently long groove 21.
