K8610-6584 Free And Total Glycerin By Gas Chromatograph

Test Method
For the quantitative determination of free and total glycerine in B-100 methyl esters by gas chromatography. The range of detection for free glycerine is 0.005 to 0.05 mass %, and total glycerine from 0.05 to 0.5 mass %. The sample is analyzed by gas chromatography, after silyating with N-methyl-N-trimethylsilytriflouracetamide (MSTFA). 
Free and bonded glycerine content reflects the quality of Biodiesel. A high content of free glycerine may cause problems during storage, or in the fuel system, due to separation of the gylcerine. A high total glycerine content can lead to injector fouling and may also contribute to the formation of deposits at injection nozzles, pistons, and valves.

Gas Chromatograph
The Biodiesel Gas Chromatography system is configured to perform and satisfy all of the requirements of ASTM D6584. Analysis takes about 25 minutes and is simple enough for an untrained operator to perform in the lab or in the field. The included PeakSimple Data System displays the calibrated results directly without off-line calculations.
