PURPOSE:To assure a flow passage selection function regardless of a column sepn. temp. so that the separated components are taken by connecting the outlet of a flow rate branching part, component capturing devices and the inlet of the flow rate branching part in a manner as to correspond the same one to one and taking the components separated by the column successively into the component capturing devices by selecting the flow passage selection part. CONSTITUTION:The flow passage branching part 8 is provided in a thermostatic chamber 1 and a flow passage selector valve 10 for selecting the flow passages for the gases passing through the branching part 8 is installed on the outside of the chamber 1 and behind the component capturing device 9. A trap using liquid nitrogen, etc. as a coolant is used for the device 9 according to the components to be taken. The sample is then introduced from a sample introducing part 2 and is separated 3 to the respective components. A conduit piping of carrier gas to be let out of a detecting part 4 is branched 8 and is captured 9 via the branch pipe 8-1 until the intended component is detected in the part 4. The conduits are so selected 10 in this stage that the conduit led out of the device 9 is held open and that the conduit led out of the device 9' for capturing the intended component is held closed. The intended 10 is captured 9 by the selection 10 when the separation of the intended component is detected.
