The invention discloses a gas chromatograph analysis method for tetrafluoroethane-beta-sultone, which comprises the following steps of: using a chromatographic instrument; taking a teflon pipe as a chromatographic column; diluting a sample by organic solvent; and leading carrier gas with the sample to pass through the chromatographic column. The gas chromatograph analysis method is characterized in that an inlet end of the chromatographic column is directly connected with a sample inlet; 50-90mm is remained to be taken as a sample gasifying room; and an outlet end of the chromatographic column is tightly connected with a detector; and detected data is quantitatively analyzed by means of gas chromatograph, so that the content of tetrafluoroethane-beta-sultone in the sample is obtained. The method has the advantages that the content of tetrafluoroethane-beta-sultone is detected by a gas chromatograph method rather than a nuclear magnetic resonance method, has the characteristics of being simple and convenient, exact, quick and reliable, and has an important practical value for the production control and the product quality control of the tetrafluoroethane-beta-sultone.
