AI Technical Summary

Technical Problem

In traditional tritium samplers, the inlet and outlet pipes age rapidly during the catalytic oxidation process. Heat transfer leads to the deterioration of the pipe materials, and condensate dripping affects the normal operation of electronic components inside the chamber.

Method used

Cooling components are installed on the catalytic converter intake and exhaust pipes, a drip tray is set up to collect condensate, and a cooling fan and air conditioner are installed inside the chamber to reduce heat in the gas path and prevent gas leakage and water accumulation.

Benefits of technology

It extends the service life of the gas path, prevents air leakage and water accumulation, improves the stability and safety of the sampler, and ensures sampling accuracy.
