Although the majority of atmospheric mercury is present in elemental form, differentiation among the three types is important due to the widely varying local impacts of each type. Often, reactive gaseous mercury will be trapped on the filter medium along with the particulate bound mercury, resulting in large measurement artifacts.

The Tekran speciation system solves this problem by removing the reactive gaseous component using a denuder before sampling the particulate mercury.

The Tekran® Model 1135 Particulate Mercury Unit is used together 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.

Provides accurate ambient air speciation for areas close to industrial sources such as waste incinerators, which often discharge the majority of their mercury emissions in particulate or ionic form.

Capable of fully automated, unattended operation with all three components being concurrently measured.
