Kovats indices were calculated using Equation (1):

where I = {\displaystyle I=}, I = Kovats retention index; n = {\displaystyle n=}, n = the number of carbon atoms in the smaller n-alkane; N = {\displaystyle N=}, N = the number of carbon atoms in the larger n-alkane; tr = {\displaystyle t_{r}=}, tr = the retention time.

Equation (1) is the main source for the calculation of Kovats index values, since the temperature was programmed.
