5E-DMA Series Direct Mercury Analyzer
The 5E-DMA Series Direct Mercury Analyzer is designed to determine mercury content in various samples, including soil, sludge, wastewater, food, produce, cosmetics, feed, fertilizer, coal, and copper concentrate. This advanced analyzer can directly measure the total mercury in both solid and liquid samples without the need for complex sample pretreatment. This approach effectively avoids the loss of mercury during the pretreatment process, prevents cross-contamination, and minimizes environmental pollution, ensuring the accuracy of the analysis data.
Compared to the traditional chemical vapor generation-atomic fluorescence spectrometry method, the pyrolysis method used by the 5E-DMA Series is more efficient, accurate, stable, and reliable for measuring mercury. This method significantly reduces labor intensity and saves up to 70% of analysis time and cost.
