Elemental Mercury Passive Sampler

The SKC 520 Series Elemental Mercury Sampler measures worker exposure levels as a Time-Weighted Average (TWA) and permits the positive analysis of elemental mercury vapour. It is designed for analysis using standard laboratory equipment, and therefore, the cost per measurement is kept to an absolute minimum compared to other samplers. The sampler only samples elementary mercury (Hg) in the vapour phase; it does not sample elemental Hg in the particulate phase or organic mercury compounds.

Mercury vapour enters the sampler by positive, controlled diffusion so that a known sample volume is taken for a given period of time. Mercury is completely adsorbed onto the solid sorbent. The sorbent capsule is then taken to an accredited laboratory where the sorbent is dissolved in acid and analyzed by flameless atomic absorption. The sampler holder is cleaned and reused, thereby reducing sampling costs.
