Speciation Sorbent Traps are available for evaluations, research, comparison with CEMMs or Ontario Hydro, and Sorbent Injection Efficiency Studies. These 10mm, extra long, and extra durable sorbent traps come with 2 types of sorbent. One sorbent collects only oxidized mercury while the other collects the elemental mercury. Moisture resistance and acid gas scrubbers come standard on these traps in order to prevent interference with the oxidized mercury.
