Determination of the blend composition ratio of gasoline to kerosene by multivariate analysis

Abstract

When a mixture of gasoline and kerosene was measured by gas chromatography, we could not accurately judge whether the measured material was gasoline or kerosene because the respective chromatograms overlapped. Therefore, to analyze the blend composition ratio (w/w) of gasoline to kerosene, some chromatograms were made using mixtures of gasoline and kerosene with known blend composition ratios. Each peak in the chromatograms was expressed by relative value to provide a data base. Next, the blend composition ratio was calculated more finely by factor score and multiple regression analysis. By this method, the blend composition ratios of gasoline-kerosene mixtures can be determined with a high degree of accuracy.
