DMA-80测汞仪的应用探讨

本文的主要实验目的是利用DMA-80测汞仪直接测定固体样品中的汞并证明其方法可靠。采用升温加热直接进行热分解、金汞齐反应，采用长、短双检测池，可直接测定固体、液体样品,汞含量在0.n×10-9～600.0×10-9范围内的样品都能被很准确地测定，每个样品测定时间约为5min。 测试结果证明其方法具可靠性。

Discussion for application of DMA - 80 Direct Mercury Analyzer

This paper mainly studies the measurement method of pyrolysis mercury with DMA-80 Direct Mercury Analyzer. Namely adopting to heat up for thermal decomposition directly, the amalgamator will react. Using the long and short two measurement cells, Solid and liquid samples can be directly measured. the mercury content of sample can be very accurately measured in the range of 0.n×10-9 to 600 ×10-9.The measurement time of each sample is for about 5 minutes. Test results proved that the method is reliable.
