PROBLEM TO BE SOLVED: To provide a chromatograph analyzer capable of reducing discharge of components other than analysis target substance after analysis and time loss due to arrangement of stabilization time so as to improve the operation rate without performing simultaneous operation of multiple devices.SOLUTION: A chromatograph analyzer comprises: an automatic injection device; a column; a pump device for supplying a moving phase; and a detector. A plurality of columns that are switchable by a switching bulb are arranged in parallel between the automatic injection device and the detector. Each of the columns individually includes a switching blub for branching the column between the pump device for supplying a moving phase and a drain, and between the drain and the detector; and has a plurality of channels. |
