Superior sample combustion for soil and sediment with the Hidex 600 OX

8 August 2022

The Hidex’s catalytic combustion chamber allows 14C or 3H in organic material to be properly trapped and counted

The Hidex 600 OX sample oxidizer delivers a superior combustion of inorganic material such as soil and sediment by using a catalytic combustion chamber operating at a high temperature of 900°C instead of an open flame. The resulting 14CO2 or 3H2O is then absorbed directly into a liquid scintillation cocktail for counting.

Accurately calculating disintegrations per minute

Many older models of sample oxidizers use an open flame, which adequately combusts tissue but fails to combust all organic material trapped in samples such as soil and sediment, or even concrete from nuclear power plants. This presents a problem when measuring residual radioactivity because an open flame delivers an incomplete combustion, leaving a residual “nugget” of sample.

When working at an analytical level with a combusted sample of a known quantity and calculating DPMs of radioactivity, it is difficult to determine how much of the material has not been combusted. The 600 OX resolves this by completely combusting samples and reducing them to inorganic material with the radiolabelled material properly extracted and counted.
