Flash evaporator and gas chromatograph

Abstract

The present disclosure relates to a technical field of analysis, and provides a flash evaporator and a gas chromatograph including the flash evaporator, which can avoid pressure buildup of a sample after vaporization and completely vaporize a sample by a heating module. The flash evaporator is applied to sample pretreatment of a gas chromatograph. The flash evaporator includes a sample inlet, a gas sample outlet, a heating module, and a flow restriction device. The heating module communicates with the sample inlet and the gas sample outlet, performs flash evaporation on a liquid sample entering the sample inlet to obtain a gas sample, and delivers the gas sample to the gas chromatograph through the gas sample outlet. In particular, the flash evaporator also includes the flow restriction device disposed in a pipeline between the heating module and the sample inlet.
