Analytical Services - Biodiesel Free and Total Glycerin Sequence

This determination of free and total glycerin in biodiesel by gas chromatography video is a series of biodiesel analysis videos created by the Analytical Services Laboratory of the Robert M. Kerr Food & Agricultural Products Center. Glycerin is a major byproduct of biodiesel production, a process called transesterification, where oils and fats are converted to fatty acid methyl or ethyl esters.
