Abstract: In a gas chromatograph 1, a back-pressure calculation processor 242 calculates a back pressure for a first detector. The pressure calculation processor 243 calculates a pressure of a carrier gas in a branching part. The back-flow determination processor 244 compares the pressure of the carrier gas in the branching part calculated by the pressure calculation processor 243 with the back pressure of the first detector calculated by the back-pressure calculation processor 242, and if the pressure of the carrier gas in the branching part is smaller than the back pressure of the first detector, the back-flow determination processor 244 determines that the carrier gas will flow back. It is therefore possible to surely know that there is a possibility that a back-flow of the carrier gas will occur, by checking the determination result of the back-flow determination processor 244.
