本文首次提出一种制造成本低、自动化程度高、测量精度好的汞／氢化物循环发生式装置。样品溶液2．5ml时分取精度≤万分之八；还原剂1．0ml时加液精度≤千分之三。具有消除水蒸汽和测定峰形拖尾以及渗微量空气于气路的功能。对测碲、硒、铅比一般批式发生器有更好的灵敏度、线性及精密度。可自动循环工作，分析速度快，120～180只样／每小时。氢化元素特征含量为0．3～0．8ng／1％吸收，精密度为0．7～1．5％（n=20～44）
For the first time, this paper presents a mercury / hydride cycle-type device with low manufacturing cost, high degree of automation and good measurement accuracy. 2.5ml when the sample solution Accuracy ≤ 800%; reducing agent 1.0ml add liquid accuracy ≤ three thousandths. With the elimination of water vapor and determination of peak tailing and infiltration of trace air in the gas function. Tellurium, selenium, lead than the general batch generator has better sensitivity, linearity and precision. Can be automatically cycle work, analysis speed, 120 ~ 180 samples / hour. The content of hydrogenated elements is 0.3 ~ 0.8ng / 1%, and the precision is 0.7 ~ 1.5% (n = 20 ~ 44)
