This apparatus uses catalyst assisted combustion techniques to give a clean and precise approach to extracting carbon-14 & organically bound tritium or ‘fixed tritium’, eg tritium contained in concretes, steels and graphites, as well as ‘free water’.
A catalyst is used to ensure complete combustion of all thermal decomposition products. These are captured for liquid scintillation assay. This technique gives greater confidence of complete combustion than ‘wet oxidation’ techniques and avoids coloured contamination of scintillation media by botanical samples.
Computer control enables remote operation of multiple or individual units even in hazardous areas.
