Biodiesel offers a renewable source of energy from various plant and animal-based feedstocks. The chemical composition of biodiesel fuels is identified through the presence of fatty acid methyl esters (FAMEs) that vary in composition based on feedstock. Biodiesel can be blended with petroleum diesel in any proportion and is a viable option in many countries. In this research, pure biodiesel and biodiesel (soybean, canola, waste grease, etc) blended with petroleum diesel, were evaluated using Gas Chromatography-Mass Spectrometry (GC-MS) on a RTX-50 mid-polar column. Various concentrations of biodiesel-diesel blends (B100, B20, B10, B5, and B2) were analyzed using Principal Component Analysis (PCA) and Partial Least Squares to investigate variables contributing to differences in sample composition.
