Abstract

In this paper, we report the quantitation of hydroprocessed vegetable oil (HVO) in petroleum diesel and biodiesel blends. To accomplish this goal. we have developed a low-pressure interface using commercially available components from original equipment manufacturer (OEM) SGE / Trajan Scientific and Medical. The low duty cycle modulation was optimized using a multivariate approach by investigating three important parameters, namely, flush period, auxiliary gas flow, and dimension of restrictor capillary (i.e., bleed). A 5-fold reduction in analysis time was accomplished, while maintaining the group-type separations by exploiting short modulation period. Successful quantitation of HVO was attained due to the inherent low sensitivity of the interface allowing for a wide linear range from 1.0% (w/w) to 100.0% (w/w). The current low pressure and low duty cycle interface exhibits simple and robust operation being particularly suited for fuel analysis. (AU)
