The MMS basically comprises a multiplexer-valve unit and a highly accurate and selective mercury detector (VM-3000 Vapor Monitor) for measurements in air and other gases Each mercury on-line system will differ in sample characteristics as well as installation conditions and operating environment. We have the experience to design systems that fully meet the requirements of your particular mercury monitoring task.
