| Abstract: | DMA-80 Mercury Analyzer can directly analyze mercury in the air concentrated on sulfhydryl cotton without any pre-processed. The accuracy and the precision of the method were tested by using the standard soil sample ESS-3,and simultaneously the method detection limit and simulated samples were measured. The results showed that the detection limit of the method is 0. 006ng,which is far below the standard discharge limit requirements（0. 1ng）,and the accuracy and precision can also meet the analysis requirement. |
