Window Analysis Optimization Of Gas Chromatographic Separation Using Different Polarity Packed Columns

Abstract

Window diagram theory has been described by Purnell and his research team in various publications. In this paper we apply this theory to optimize a separation of complex mixture containing propylene oxide, 1-hexene, cyclohexene, tert. amylmethyl wther, 4-octene, 1-octyne, 1-nonene, p-xylene and n-decane by using two different polarity serial columns; squalane (SQ) as a non-polar solvent and Diisobutyl phthalate (DBP) as a polar solvent. A baseline separation of all mixture components is achieved following window analysis that defined the necessary relative and total column lengths. Identical chromatograms for both options: (1) SQ = front, (2) DBP=front are successfully obtained.
