2results about How to "Guaranteed normal sampling" patented technology

The application relates to a carbon tritium sampler, which relates to the technical field of sampling equipment and comprises a box body, a sampling head installed on the box body, a plurality of sampling bottles sequentially communicated through a sampling gas path installed in the box body, a circulating cooling device, at least one exhaust pipe and an exhaust passage communicated with the outside world. The sampling bottle located at the first position is communicated with the sampling head through a fan, and the sampling bottle located at the last position is communicated with the outside world. The circulating cooling device comprises a cooling liquid circulating assembly and a cooling fan for cooling the cooling liquid circulating assembly. At least one exhaust pipe is installed in the box body, the exhaust pipe is provided with an exhaust passage communicated with the outside world, the air inlet of the cooling fan is communicated with the outside world, and the outside air is exhausted through the cooling fan, cooled to the cooling liquid circulating assembly and then enters the exhaust passage. The application can effectively and quickly cool the solution in the sampling bottle, is not affected by the temperature in the box body, improves the sampling stability, maintains the normal sampling and the like.
