Short summary
This study was undertaken to demonstrate that a cation exchange membrane (CEM) material used for sampling reactive mercury (RM) does not possess an inherent tendency to collect gaseous elemental mercury (GEM). Using a custom-built mercury vapor permeation system, we found that the CEM material has a very small GEM uptake of approximately 0.004 %, too small to create a significant artifact. We also found that a representative RM compound was collected by the CEM material with high efficiency.
