The HC-3C tritium sampler is suitable for sampling tritium water vapor in ambient air. The freezing method is used to collect moisture in the air, and two parallel samples are taken, equipped with a measurable condensate collection bottle, which not only ensures the complete capture of moisture in the sampled air, but also facilitates the sample preparation and liquid scintillation measurement process. This sampler can achieve intermittent sampling and continuous sampling, and can display the current cold trap temperature value, oxidation bed temperature value, instantaneous and cumulative flow rate, sampling time, fault information, etc. in real time. It also has timing control and data storage functions. If necessary, by adding an additional high-temperature catalytic oxidizer, the sampler can be transformed into an atmospheric HTO-HT discrimination sampler.
