英文摘要 | the identification of unknown compounds in complex samples is very difficult. comprehensive two-dimensional gas chromatography (gc x gc) provides very good resolution and improved identification reliability. mass spectrometry is a powerful identification tool and retention index data are another good approach to this end. in this study, a second-order polynomial was used to calculate retention index data based on n-alkanes beyond the region of the 'isovolatile' curve in gc x gc, and the results in the 2nd dimension were validated by using the same stationary phase column in one-dimensional gc. to test the usefulness of the method, volatile compounds in a tobacco leaf extract fraction were analyzed using gc x gc, and 60 compounds were identified on the basis of their retention indices. |
