FCTC14Organic Tritium Carbon Pre treatment Sample Preparation Equipment

Product Introduction：

Tritium and carbon are the main nuclides emitted from nuclear current discharge, and nuclear facilities may release a certain amount of tritium into the environment under certain circumstances, causing certain pollution to the environment. The tritium in biological samples consists of two parts, namely free water tritium (TFWT) and organic bound water tritium (OBT).¹⁴C participates in various biological cycles and is easily deposited in the food chain. The monitoring of radiation environment around newly built nuclear power plants requires the monitoring of tritium and carbon-14 in organisms.Environmental requirements for tritium and carbon-14Analyze the pollutants, with specific activity ranges from environmental grade toILW(Intermediate level of radioactivity). The common method is to combine organic tritium and carbon through oxidative combustion-14Convert the sample intoH₂O(³H)andCO₂(¹⁴C)Furthermore, regardingH₂O(³H)andCO₂(¹⁴C)Collect and analyze. This device has the characteristics of program-controlled heating, independent control of the combustion zone and catalytic zone, high reaction rate and recovery rate.
