Tekran - Model 1135 - Particulate Mercury Module - Brochure

The Tekran Model 1135 Particulate Mercury Unit is used with the Model 1130 Speciation Unit and the Model 2537 Mercury Analyzer to simultaneously monitor particulate bound mercury (HgP ), elemental mercury (Hg0 ) and reactive gaseous mercury (RGM) in ambient air. The system allows fully automated, unattended operation with all three components being measured concurrently. Although the majority of atmospheric mercury is present in elemental form, differentiation among the three types is important due to the widely varying local impact of each type. (Particulate and reactive gaseous mercury have higher wet and dry deposition rates than does elemental.) Ambient air speciation is of particular interest close to industrial sources such as waste incinerators, which often discharge the majority of their mercury emissions in particulate or ionic form. The Tekran speciation system has also been used in Polar Regions to delineate the conversion of elemental mercury to other forms during polar sunrise.
