一种用于800M定量核磁共振仪的氦气回收系统

Helium Recovery System for 800M qNMR

针对我国氦资源短缺问题的现状,中国计量科学研究院对800M定量核磁共振仪和离子回旋共振质谱仪进行改造,加装了氦气回收系统,并配合氦液化系统,可以达到循环使用氦气(液)的目的,且有较大经济效益。结果表明,每年的回收价值约在十万元左右。

Current situation of helium shortage in China,helium of 800M qNMR and Ion Cyclotron Mass Spectrometer was recovered by National Institute of Metrology,helium(liquid helium)is recycled with helium liquefaction system,there are also huge economic benefits.And the result shows that,it would save about RMB 10,000 every year.
