| Abstract: | Seven taste and odor compounds were determinated using Solid Phase Extraction and Gas Chromatography-Mass Spectrometry.The Solid Phase Extraction method for pre-processing operations was optimized.The Seven taste and odor compounds were condensed by HLB SPE-column and eluted with 2 mL of dichloromethane. The results showed that it had a good linear relation in the range of 0.004-0.1 mg/L with a high sensitivity and a good precision.The limit of detection of this method was ranged from 1×10-6 to 2×10-6 mg/L. The recoveries of the method were from 85.9% to 108.6%. It was successfully applied to analyze taste and odor compounds of surface water. |
| Keywords: | taste and odor compounds Solid Phase Extraction Gas Chromatography-Mass Spectrometry |
