Tritium carbon sampler

The utility model discloses a tritium carbon sampler which comprises an air loop, the air loop comprises a flow meter, an air filter, a plurality of sampling bottles and an air pump which are connected in sequence, one end of the flow meter far away from the sampling bottles is an air inlet, one end of the air pump far away from the sampling bottles is an air outlet, and the tritium carbon sampler further comprises a cooling loop, and the cooling loop is used for reducing the temperature of the sampling liquid after heat exchange with the sampling liquid in the sampling bottle. According to the utility model, the cooling loop is arranged to cool the sampling liquid in the sampling bottle, so that the volatilization process of the sampling liquid in the sampling bottle is slowed down, and the problem that the cooling liquid flows back during the operation of the sampler is solved. 本实用新型公开了一种氚碳取样器，包括空气回路，所述空气回路包括依次连接的流量计、空气过滤器、多个采样瓶和空气泵，所述流量计远离采样瓶的一端为进气口，所述空气泵远离采样泵的一端为出气口，还包括冷却回路，所述冷却回路用于与所述采样瓶内的采样液进行热交换后降低采样液的
