Abstract
A fast method based on High performance liquid chromatography technique for the estimation of Saturates, Olefins, Conjugated dienes and Aromatics in Cracked gasoline samples has been developed. In this work, the focus was on choosing the right reference standard against which olefin could be estimated. The olefin reference standard was first shortlisted using Nuclear Magnetic Resonance spectroscopy and Gas chromatography based Simulated Distillation analysis as per ASTM D2887. The values estimated against shortlisted standards using HPLC were compared with values obtained using standard Flourescent Indicator Adsorption(FIA) based ASTM D1319 method to select one. The aromatics were estimated against o-Xylene.
