Summary:By using post-column reaction GC, a method for accurate and direct characterization of musty odor substances (2-methylisoborneol and geosmin) in a candidate standard solution has been developed. Because the GC system gives a response depending on the number of carbon atoms constituting the organic compound by combustion and conversion to methane, naphthalene and diethyl phthalate, purity of which had been accurately assessed, were used as reference materials for calibration. To verify the method, concentrations of 2-methylisoborneol and geosmin in the sample determined by the method were compared with the concentrations calculated based on gravimetric mixing that is one of the general methods for the characterization of the organic standard solutions. The analytical results of each analyte obtained by the two methods agreed within a deviation of about 0.5 % or less.
