ASTMMethod D6584-00 and EN14105 (Biodiesel)
Determining Free and Total Glycerin in B100 Biodiesel
Methyl Esters by GC
In the manufacture of biodiesel fuel, triglycerides are split into
their monoalkyl ester components via transesterification. The
fatty acid monoalkyl esters can be used as fuel in diesel engines.
Amounts of free glycerin and total glycerin indicate the quality of
the conversion of the oil or fat to monoalkyl esters. D6584-00 is
a test method for quantitative determination of free glycerin,
total glycerin, and mono-, di-, and triglycerides in biodiesel fuel
methyl esters by GC, after silylation of the sample with
N-methyl-N-(trimethylsilyl) trifluoroacetamide (MSTFA).

ASTMMethod D6730-01 (Determination of Individual
Components in Spark Ignition Engine Fuels)
ASTM Method D4059-96 is used for determining PCB concen-
trations in various types of transformer oil, using GC/ECD
detection. The analyst must dilute transformer oil samples in a
solvent prior to injection. The oil in the sample has been shown
to quench the ECD. Calibration mixtures of PCBs in transformer
oil must be prepared and diluted identically to eliminate the
detector quenching bias resulting when samples are analyzed.
We prepare these solutions in a mineral oil-based transformer oil
(Exxon® Univolt® N-61), which has been tested to ensure it is
PCB-free.
