Free Glycerol and Total Glycerin in Biodiesel Tester ASTM D6584
Product Model: JF6584
Product Introduction
The content of free glycerin and total glycerin reflects the quality of biodiesel, due to the separation of glycerin, too high content of free glycerin may cause some problems during storage or in the fuel system, and too high content of total glycerin can cause injectors fouling, and deposits can form on injector nozzles, pistons, and valves. The instrument is the first of its kind in China. It is calibrated using two sets of domestic standards and 4 reference materials. By comparing with the standard specifications of monoolein, diolein and triolein, the measurement of monoglyceride is carried out respectively. Determination of lipids, diglycerides and triglycerides. The usual conversion factors are applied to mono-, di-, and triglycerides to calculate the amount of bound glycerol in the sample.
