Tritium and carbon-14 collection device

The utility model relates to the field of radio element detection devices, in particular to a tritium and carbon-14 collection device, which includes at least two collection channels, and each of the collection channels includes an oxidization furnace, a vapor absorption bottle, a carbon dioxide absorption unit and a cold tap. The inner wall of the oxidization furnace adopts a stainless steel sampling heating pipe. The stainless steel sampling heating pipe, the vapor absorption bottle and the carbon dioxide absorption unit are respectively provided with a gas inlet and a gas outlet. The gas inlet of the vapor absorption bottle is communicated with the gas outlet of the stainless steel sampling heating pipe, and the gas outlet of the vapor absorption bottle is communicated with the gas inlet of a carbon dioxide absorption bottle, and the vapor absorption bottle is arranged in the cold trap. A high-temperature oxidization area, a buffering area and a high-temperature catalysis area are sequentially arranged in
