The tritium activity in the ecosystem is measured on various matrices. The tritium bound to organic matter represents the tritium fixed by the operation of living objects. The sample should be prepared to preserve the tritium abundance with no isotopic fractionation. Transformation of the test sample should be conducted in order to obtain the highest possible combustion water yield, with no isotopic exchange. The test samples to be used should be sufficient to perform the measurements with the lowest possible detection threshold.
