Objective: This paper reports a Head-space GC method for determination of enthanol, hexane, benzene,toluene, methyl cyclohexane ,xylene, styrene, divinyl benzene in macroporous resin extractions. Method: The analytical column was DB-1（60m×0.32mm，1μm）.The injector temperature was 180 ℃ and the detector temperature was 250℃. The column temperature was programmed raised. The carrier gas was nitrogen and the solvent was 20%–50% dimethyl sulfoxide. Results: The stand curve were linear for each solvents in the range of each consistency. The average recoveries were all more than 75%. Conclusion: This method is simple, rapid and precise, it is suitable for measurement of residual solvents in macroporous resin extracts.
