Development of direct CO2 absorption system for radiocarbon dating and bio-based carbon determination in biogenic-synthetic products [PDF]

Nuclear Technology and Radiation Protection, 2022
This work presents a development of a new radiocarbon dating system based on CO2 and liquid scintillation counting. The system is flexible enough to be applied in different fields such as radiocarbon dating (up to about 32 000 years span ...

Rapid assay of labeled free fatty acids in mixtures of labeled lipids

Journal of Lipid Research, 1968
The fatty acids in lipid mixtures are adsorbed on dehydrated hydroxy-charged ion exchange resin, the other lipids are removed by washing with solvent, and the adsorbed fatty acids are released with quaternary ammonium base for counting. All manipulations

A flow-through method for scintillation counting of carbon-14 and tritium in gas-liquid chromatographic effluents

Journal of Lipid Research, 1962
A method for radioassay of gas-liquid chromatographic effluents by scintillation counting has been developed. A cartridge filled with anthracene crystals is used as a “flow-through” radiation detector. Upon leaving the column, the effluent is passed over
