摘要
粮油中汞含量超过一定限量 ,食用对人就会造成危害。但因测定仪器的灵敏度较低 ,致使检出结果不够准确 ,经改进后 ,研制的高灵敏度测汞附件与原系统配合使用 ,提测汞灵敏度达 40倍 ,完全克服了原系统出现的缺点。新方法灵敏 ,操作简单 ,结果准确 。
It is harmful for human that the mercury contents in grain and oil exceeds the base standard.The sensitivity of some measuring instruments is too low that the inspection results are inaccurate.A sensitive annex for inspecting mercury contents is developed to conjugate with the original system.It completely overcomes the shortage of original systems,and promotes the sensitivity of mercury measurement with 40 times.The new technique has high sensitivity ,simple operation,accurate results and good practicability.
