Calculation Program of Kovats Retention Index Values Based on Those of Known Compounds

Abstract

According to the progress of the technique of GC analysis, Kovats Retention Index (KI) together with GC/MS analysis has become more important for the identification of volatile compounds. In this paper, a new method for the calculation of KI values has been reported. Based on known compounds, KI values of the components of a chromatogram were calculated without using n-paraffins as reference compounds. This calculation program of KI values was applied to the volatile compounds of oxygenated fraction of Shiroyanagi navel oil and gave good reliability.
