Designed as an instrumental replacement for Ontario Hydro Method, this is a good tool for testing certification of permanent CEMM's, and on-site performance evaluation of Mercury Control Technologies.
IRM-915 Mercury Stack Monitor has recently passed RATA (Relative Accuracy Test Audit). Result are available per request.
Real-Time continuous mercury monitor is based on the analytical approach of Thermo catalytic conversion and Atomic Absorption for detection of mercury with Zeeman background correction. This approach requires no preconcentration on gold eliminating the associated problems. The use of multipath cell combined with "dry" converter provides highest sensitivity with no interferences from the combustion gas matrix. High converter temperature (700°C), short residence time and up to 1:100 dilution prevents Mercury atoms from recombining with any "active" species generated due to high temperature decomposition of flue gas.
Heated Probe and Heated Filter with Dilution/Conversion assembly are used for "High" or "Low" particulate loading. Results are reported on "wet" basis as regulation requires.
Mercury speciation is possible with this system.
