The Raddec HBO2 is a fully-integrated Hyperbaric Oxidiser System that has been designed to quantitatively oxidize combustible materials to water and carbon dioxide using pressurised oxygen in a precision engineered, closed-vessel.
These systems are routinely used to extract volatile radionuclides from a range of materials as part of waste characterisation in the role of nuclear decommissioning, waste characterisation and environmental monitoring.
Combustible materials such as plastics, rubber, oil, resins and soft wastes, are effectively decomposed and oxidised. In addition, foodstuffs and environmental materials such as biota are also readily decomposed to provide representative samples of Tritium and Carbon-14 for analysis.
Complete and clean oxidation of organic-rich materials (foodstuffs, marine and freshwater fish, meat, vegetation, wood, oils, plastics, and soft wastes)
The heart of the HBO is a five-litre precision engineered pressure vessel designed to safely operate up to 95 Bar. The system incorporates a user-friendly manual gas handling system including user-adjustable pressure regulation and flow control.
A unique feature of the HBO2 include a novel, easy-to-use door-closure mechanism with an integrated combustion viewing window and pressure and temperature displays for real-time monitoring. Four safety interlocks and a dual pressure protection system ensures that the system functions safely.
All key combustion-related parameters are recorded and displayed in real time using a Labview Program.
The product gases produced during complete oxidation of materials are quantitatively collected through a cryo-trapping system that uses vacuum-grade glass condenser tubes fitted inside a graphite heat-exchanger block.
The whole process from loading through ignition, venting and vacuum extraction and cleaning typically takes 1 hour per sample.
HBO2 - Key features:
The HBO2 hyperbaric oxidiser is a proven analytical device that has been in routine use in radioanalytical laboratories since 2012.
Complete combustion of samples takes less than one and the oxidation of large samples offers improved ‘Limits of detection’ compared to slower thermal oxidisers - this extends analytical options for Environmental Monitoring, Nuclear Decommissioning and Fusion Reactor operational support.
Clean tritiated water is extracted after combustion - Tritiated water is available for analysis by Liquid Scintillation Counting or Helium-3 in-growth mass spectrometry.
