Abstract

The aim of the research was to test the generalized direct liquid scintillation spectrometry (LSC) method for bio-origin determination by measurement of C-14. Examples of diversified items with known and unknown bio-origin were measured by liquid scintillation counting and analyzed by procedures, developed for fuel samples. Bio-origin of fuels, lubricants and monomer resins were successfully determined via direct LSC method after simple sample preparation with acceptable accuracy and trueness despite their diversity in color, viscosity, density or chemical composition.
