Abstract:
1. A thin-layer chromatography (TLC) method for detecting an amount of one or more suspected bound glyceride contaminants in a fuel sample wherein the bound glyceride contaminants comprise monoglycerides, diglycerides and triglycerides using a fluorescent lipophilic dye comprising the steps of: obtaining the fuel sample; separating the fuel sample along with a standard sample of the suspected contaminants on one or more coated TLC plates; submerging the TLC plates in a hydrophobic nonaqueous solution comprising the fluorescent lipophilic dye to stain the plates; drying the stained plates; dipping the dried plates in a bleach solution; visualizing one or more bands on the one or more coated TLC plates using an UV lamp; and determining the amounts of the one or more suspected bound glyceride contaminants by comparing a region of interest in the one or more bands on the one or more coated TLC plates for the standard and the fuel sample.
