AB  - This paper aims to establish a method for the determination of sulfur dioxide in 
      sulfur fumigation Chinese herbs. Sample powder and hydrochloric acid solution 
      were isolated by paraffin layer in order to avoid early reactions, with the 
      generation of sulfur dioxide, headspace with airtight needle was used to transfer 
      sulfur dioxide into gas chromatograph, and detected with thermal conductivity 
      detector. The analytical performance was demonstrated by the analysis of 12 
      herbs, spiked at four concentration levels. In general, the recoveries ranging 
      from 70% to 110%, with relative standard deviations (RSDs) within 15%, were 
      obtained. The limit of detection (LOD) was below 10 mg x kg(-1). Standard 
      addition can be used for low recovery samples. The method is simple, less 
      time-consuming, specific and sensitive. Methods comparison revealed that gas 
      chromatography is better than traditional titration in terms of method 
      operability, accuracy and specificity, showing good application value.
