This application describes a method for determining the ester and linoleic acid methyl ester content of fatty acid methyl esters (FAME) intended for use as pure biofuel or as a blending component for heating and diesel fuels. The method is suitable for FAME con- taining methyl esters between C14 and C24. This applica- tion used the Agilent 6850 System and HP-INNOWax column; calibration was achieved with internal standards of methyl heptadecanoate. After analyzing several differ- ent types of biodiesel, excellent precision was obtained, exceeding the EN14103 method specifications.
Gas chromatography (GC) with a split/splitless inlet and FID is used to determine the ester and linoleic acid methyl ester content of fatty acid methyl esters (FAME) intended for use as pure biofuel or as a blending component. The method described in this document utilizes the Agilent 6850 System equipped with an HP-INNOWax column and calibration achieved with internal standards of methyl heptadecanoate.
This note describes how to determine the ester and linoleic acid methyl ester content of fatty acid methyl esters intended for use as pure biofuel or as a blending component for heating and diesel fuels.
You must accurately weigh approximately 250mg of the sample in a 10-mL vial before adding the calibration solution.
The inlet temperature must be set to 250°C.
