Abstract

The invention provides an organic tritium oxidation combustion tube and an organic tritium oxidation combustion method. The organic tritium oxidation combustion tube comprises a long quartz tube divided into a first part and a second part, and a short quartz tube accommodated in the second part, wherein the first part is provided with a sample boat to form a sample combustion area; the short quartz tube is filled with a catalyst to form a catalytic oxidation area; the sample combustion area and the catalytic oxidation area are heated by a heating device; the tail end of the tube of the first part forms a first gas inlet; and a second gas inlet and an exhaust outlet are formed in a tube wall of the second part. The organic tritium oxidation combustion method achieved by the organic tritium oxidation combustion tube can carry out ventilation at the two ends, so that a low oxygen content in the sample combustion area and a high oxygen content in the catalytic oxidation area are ensured, the problems such as open fire combustion and insufficient sample oxygenation are effectively avoided in a sample treatment process, generated water is clear in color, the sample treatment capacity is large, the device is reasonable in structure, safe, practical and efficient, and a catalyst is convenient to replace.

Description

technical field [0001] The invention relates to the field of organic tritium activity measurement, in particular to an organic tritium oxidation combustion tube and an organic tritium oxidation combustion method. Background technique [0002] The process of organic tritium activity measurement is that biological samples are freeze-dried, high-temperature oxidized and burned, the generated water is collected, and finally the tritium activity in the generated water is measured by liquid scintillation. One of the difficulties in this series of processes is how to achieve sufficient oxidation of organic tritium and complete capture of generated water. At present, there are still some problems in the oxidative combustion of organic tritium and the capture of generated water. For example, biological samples are prone to open flame combustion, quartz oxidation combustion tubes are prone to bursting, samples are incompletely oxidized, and incomplete combustion products accumulate in...
