ASTM D6584 - Determination of Total Monoglyceride, Total Diglyceride, Total Triglyceride, and Free and Total Glycerin in B-100 Biodiesel Methyl Esters by Gas Chromatography (GC)


We perform biodiesel quality testing by ASTM D6584 to determine the quantity and types of glycerin in biodiesel using gas chromatography (GC). High free glycerin content in biodiesel may cause problems during fuel storage, or in the fuel system, due to separation of the glycerin. A high total glycerin content can also lead to injector fouling and may contribute to the formation of deposits at injection nozzles, pistons, and valves.

Sample quantity required: 25 ml
