Carbolite MTT Carbon14-Tritium Furnaces


The Carbolite MTT Carbon14-Tritium Furnaces 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.

Standard features

  • 2 quartz glass work tube assemblies
  • 6 combustion boats
  • Three sets of glass gas bubblers (12 in total)
  • All connectors including the molecular sieve waste aerosol trap
  • Unique catalyst optimisation manifold
  • 6 copper wire catalysts
  • 3508P1 20 segment programmable temperature control for sample specific combustion protocols
  • Over-temperature protection of both heated zones
  • RS485 communications & control
  • Eurotherm iTools allows software storage & recall of specific sample protocols
  • Free from plastic or rubber components into which tritium can migrate
  • A comprehensive process instruction manual
