5E-DMA3000 Direct Mercury Analyzer is used to determine mercury content in soil, sludge, waste water, food, produce, cosmetics, feed, fertilizer, coal, cooper concentrate, etc. It is able to directly measure the total mercury in solid and liquid samples without the need of complex sample pretreatment, effectively avoiding the loss of mercury in the pretreatment process, cross contamination and experimental environmental pollution, and ensuring the accuracy of the analysis data. Compared with the traditional chemical vapor generation- atomic fluorescence spectrometry method, the pyrolysis method is more efficient, accurate, stable and reliable in measuring mercury, which can greatly reduce labor intensity, and save 70% of analysis time and cost.
