| Preliminary studies of biodiesel samples by a high speed LC/MS system demonstrated that the LC/MS method not only reduced the analysis to 20 minutes but also revealed information about higher MW compounds in biodiesel, while still detecting many low MW chemicals, including FAMEs, at high sensitivity. ESI interface was the primary ionization technology. The cone wash kept the interface clean from contamination and clogging by residues of the complex biodiesel samples.
Future studies will be focused on two fronts: 1) fine-tuning the separation conditions to further separate the components from the early eluting, low MW compounds; and 2) identification and quantification of the components found in the TICs.
