Agilent Technology is a provider of technology, supplies, software and services to the life science and chemical analysis market. One such application of Agilent's chemical analysis was provided in using biodiesel blends utilizing the companies Heart Cutting 2d Gas Chromatography.

The analysis of the fatty acid methyl ester or FAME content in biodiesel samples is described using a heart-cutting two-dimensional gas chromatographic system. A Capillary Flow Technology Deans switch is used to interface a primary nonpolar capillary column to a secondary polar capillary column. The primary column separates most of the petroleum hydrocarbons from the FAMEs. The FAMEs are selectively transferred to the secondary column, where they are completely resolved from the remaining hydrocarbon matrix. The instrument is calibrated using the total response of all separted FAME peaks over a range of 1 to 25 volume percent. After calibration, a sample of commercially blended B20 biodiesel is analyzed.
