| Abstract: | A stable isotope dilution technique based on purge-and-trap coupled to gas chromatography with mass spectrometric detection was developed and optimized for the trace determination of the typical odorous compounds,geosmin(GSM) and 2-methylisoborneol(MIB).The selection of quantitation ions and the factors of temperature program,the sample purge temperature,salt content on the extraction of odorous compounds were studied.Under the experimental conditions,the optimal operating conditions were the addition of 20... |
