Project TitleMeasuring Bound Glycerides in Biodiese
Track Code2008-010
Short Description

The University of Texas at El Paso seeks a licensing partner for a dye-based analytical technique to determine the amount of unreacted starting materials in a biofuel composition for improved biofuel quality.


This invention uses a fluorescent dye to detect residual starting materials in a biofuel. This allows for the amounts of starting materials to be adjusted, thus resulting in a higher quality biofuel.
