Abstract

Recently developed direct LSC method for the biogenic fraction determination in biodiesel samples was evaluated. Intercomparison samples had the unknown composition of biomaterials/fossil fuels and a broad range of quench levels. Reliable results were obtained with the direct two-step LSC method for the samples with a quench level of roughly 50 channels above the SQP(E) limit of the method’s applicability. The Internal Standard method for the detection efficiency determination provided better accuracy, additionally lowering the SQP(E) limit of the method’s applicability. The adapted two-step method’s calibration via Internal Standard technique was tested on samples with sunflower seed biocomponent.
