✦ Synopsis

Gas chromatography

Theory Mathematical dead time Methylphenylsiloxane stationary phases Constants of the n-alkane retention time curve The column dead time and the constants of the n-alkane retention time curve in gas-liquid chromatography are calculated by the iterativemethodonseriesof OVwlymethylphenyl-where Z and t R are, respectively, the carbon number and the uncorrected retention time of the n-alkane examined. silicones with an increasing percentage of phenyl substituent. The values obtained are in good agreement with thosecalculated by the methods of Groblerand Kaiser isnd with the experimental ones reported in the literature for stationary phases studied at 12OOC and 15OOC. The scatter of experimental retention times of n-alkanes and ty and b and I : and Kovats retention indices are calculated.
