摘要
研制了一种全封闭式的半自动冷原子荧光测汞仪。介绍了仪器几个主要部分的构造,原理和性能。样品测定后,信号经过A/D转换器和微机数据处理系统,以数字显示和打印出所测得的结果。测试结果表明,检测下限可达1×10^(-11)g/mL Hg。仪器可用于各类样品中痕量汞的测定。
A semiautomatic cold-vapour atomic fluorescence mercury measurement instrument has been developed. The construction, principle and performance of several main parts are described. After samples are determined, output signals are transferred to A/D converter and data-processing system. The final results are displayed on a digital display and printed on a recorder. The detection limit for Hg can reach 1×10^(-11)g/mL. The instrument can be used for the determination of trace mercury in various kinds of samples.
