Abstract:
The Hidex Biofuel Method, a direct liquid scintillation counting (LSC) approach for determining biogenic carbon in fuels without a fuel-specific background sample. The mix-and-measure method combines TDCR output with an external-standard quench parameter to reliably predict background and counting efficiency for each unknown. Samples are prepared by mixing fuel with scintillation cocktail and counted in Hidex 300SL or ULLA TDCR instruments. Across fuels and blends spanning ~1–100 bio-%, results matched accelerator mass spectrometry, with detection limit down to ~1 bio-%. In addition, solid and strongly coloured liquid samples can be measured using Hidex Oxidizer and ULLA LSC counter.
