A new measurement technique which can be applied to determine rare gas Kr and Xe under the order of ppm by ICP-MS has been developed by our group. The gas introduction apparatus were designed and relevant analysis parameters were optimized. On the base of these processes, the sensitivity of Kr and Xe analysis reached (0.6-1) ×10^6cps whenair sample were directly introduced at the sampling rate of 40mL/min. The detection limit of Kr and Xeisin the oder of 10^-9L/L and 10^-11L/L, respectively. 展开更多
