The Cost Benefits of Direct Mercury Analysis

Let’s take a more detailed look at the cost of analysis comparison between a dedicated mercury analyzer and one using Direct Mercury Analysis. It’s also worth noting that there are three approved methods using this approach - EPA Method 7473 for solid samples and liquids, ASTM method D-7623-10 for total mercury in crude oil using combustion gold amalgamation and cold vapor atomic absorption method and ASTM 6722-01 for coal combustion products.

Determination of trace levels of Hg is a must

The determination of trace levels of Hg is a must and frequently measurements are performed by converting Hg to a vapor and measuring its concentration either by atomic absorption or by atomic fluorescence. DMA-80 Direct Mercury Analyser has proved its superb performance in applications for a plethora of samples, such as animal tissues, atmospheric particulate, coal, fish, hair, sediments, soils, vaccines, etc. Even speciation analysis could be performed when associating the DMA-80 with a proper extraction procedure.
