Cold Vapor Atomic Florescence is a highly sensitive measurement method employed in a Mercury Continuous Emissions Monitoring System (CEMS). This is just one of the techniques used to measure such low concentrations in the U.S., and there are many parallels to the recent European directives for Large Combustion Plants and Waste Incinerators. The need for lower level performance and qualification, as has been seen by the regulations and implementation in the U.S. and E.U. alike, is on the increase as the global community looks to decrease Hg emissions to their lowest level into the future.
