The utility model provides a flash-evaporation gasification sampling device in a gas chromatographic analyzer, which belongs to the technical field of gas chromatographic analyzers and solves a problem that control for flash-evaporation temperature and output flow rate in the prior art is inaccurate. The flash-evaporation gasification sampling device comprises a high-pressure gas cylinder which is connected with a flash evaporator, a sampling valve, a chromatographic column and a detector in sequence, wherein temperature, output pressure and output flow rate of the flash evaporator are automatically adjusted and controlled by a plurality of control modules. By virtue of the existing operation interface control of the apparatus, the flash-evaporation gasification sampling device has the advantages that operation is convenient, temperature, pressure and flow rate are accurate to control and the like.
