Hidex has developed a revolutionary novel method for detection of biogenic carbon-% in fuels. Fossil based fuels are increasingly replaced by fuels of biologic origin, such as hydrotreated vegetable oil (HVO). Percentage of biogenic carbon component in fuel was traditionally determined either by sending samples for accelerator mass spectrometry (AMS) in a third-party laboratory or liquid scintillation preceded by benzene synthesis. The direct detection of biofuel by LSC is able to overcome many limitations of traditional biocarbon quantification as liquid fuel samples can be measured directly after mixing with scintillation cocktail. Hidex biofuel method improves upon direct LSC measurement by bypassing the need for a background sample and providing individual calibration for each customer. It uses the patented Hidex Biofuel Algorithm to deduce the background CPM and counting efficiency.
