Split 101 1 µL 220C. ASTM D6584 is a method that focuses on the free glycerin and. The Analysis of Glycerin and Glycerides ASTM D6584 Peter Morgan Thermo Fisher Scientific Runcorn Cheshire UK Introduction Biodiesel is routinely used to supplement petroleum diesel due to the high cost of crude oil. The limit of detection and. Method using periodateacetylacteone derivatization was developed using UV. The method was validated according to USP and ICH guidelines.

It showed high sensitivity reproducibility repeatability accuracy and had linear behavior in the range of concentrations expected for both compounds.

The addition was slow and proceeded for approximately 20 min. Glycerin PG DEG and EG have similar physical properties such as sweetness and viscosity which facilitates the adulteration process. Another method of glycerol determination might be GLC of glycerol triacetate.
