Automated Standard and Sample Preparation for Multiple Gas Chromatographic Analyses of Biodiesel
Abstract:
An approach to automating the biodiesel standard and sample preparation prior to GC analysis is presented using the enhanced capabilities of the Agilent 7693A Automated
Liquid Sampler (ALS). A derivatization protocol for the silyation of glycerol, mono-, and di-glycerides was developed for the 7693A ALS using a procedure described in the
ASTM D6584 and EN14105 methods [1,2]. A second automated protocol was developed for adding an internal standard to biodiesel samples prior to the fatty acid methyl
ester (FAME) analysis according to the EN14103 method [3]. The resulting calibrations and GC sample runs of these methods shows excellent comparison to manual
preparation methods.
