Abstract: PURPOSE: To make it possible to separate trace amount of sample, to separate many components in a single sample and to detect it online by providing inlet and outlet block and a connecting member adapted to connect to a capillary in a cartridge. CONSTITUTION: A cartridge 10 has two flat plates 30, 31 of rectangular shape and including ends 32, 33 raised along the entire boundaries. An inner chamber having sufficient depth to accommodate capillary tubes 36 in recess parts 34, 35 specified by the ends 32, 33 in contact when the cartridge 10 is assembled is formed. The tube 36 is formed at least in one loop-like ring state and the loop is regulated to be extended to cover the most of the region of the cartridge 10. The two plates 30, 31 of the cartridge 10 respectively have windows 46, 46, a vertical optical path is formed on the flat surface of the plate when the plates 30, 31 are connected, and disposed to cross the tube at the detecting point near the one end of the tube. The wide areas of the plates 30, 31 and the plate material having expansion coefficient similar to that of epoxy and glass expedite the stabilization and average of the temperature difference along the length of the tube.
