A non-aqueous reversed phase (NARP) HPLC method using ELSD was developed for the determination of the type of feedstock and detection of feedstock adulteration in the biodiesel synthesis. This method would allow the manufacturer to determine what type of vegetable oil he is using, or if the oil has been adulterated. This is important since the need for imported feedstock is increasing do to increasing demand for biodiesel. Examples of various biodiesel feedstock and feedstock adulteration are shown using this method.
