| Abstract: | The application of gas chromatography is used to determine sodium cyclamate in beverages. The sodium cyclamate can be reacted with nitrous acid in the medium of sulfuric acid. Having been distilled with n-hexane,it is determined by gas chromatography.The results show good linearity (r=0.9999)with the concentration range of 0.25～1.25ug,the recovery rate is 83% . |
