摘　　要：本文采用金涂层石墨管、氢化物石墨炉进样系统及流动注射氢化物发生器,直接测定了部分环境和生物试样中的痕量汞,方法简便快速,重现性好,准确度高,具有高的实用价值。特征质量:5.8×10^(-11)g;检出限:2×10^(-11)g;分析速度:50样/小时。Using a gold-coated graphite tube, a sample inserting system for hydride generation graphite furnace and a flow-injection hydride generator, trace mercury in samples of environment and organism has been determined directly. The method is simple, convenient, and of good precision and high accuracy. It is a very practical method for the analysis of trace mercury. The analytical frequency is 50 samples per hour. The characteristic mass is 5.8×10^(-11)g and detection limit is below 2.0×10^(11)g.
