RP-M324 Analyzer for "Direct" thermal analysis of Sorbent Traps for monitoring Hg emissions from coal-fired power plants

RA-915+ with RP-M324 is designed for field on-site or laboratory “Direct” testing of carbon tubes for Sorbent Trap Monitoring of Hg emissions from coal fired power plants. US EPA validated thermal decomposition is referenced in appendices K part 75 of the Clean Air Mercury Rule. Atomic Absorption technology is used for no sample preparation analysis. Analysis time is less than 2 minutes per sample. No liquid chemicals or gas required, no chemical waste is generated.

In addition to Sorbent Traps, analyzer could be used for "Direct" testing of ash, coal, and Ontario Hydro method generated liquid samples. Mercury Speciation is available.
Multi point calibration protocol conforms to EPA Performance Based Criteria Method.

RA-915+ with RP-M324

A sorbent Trap tube is cut and sorbent is transferred onto a quartz ladle. The ladle is inserted into the analyzer thermo catalytic conversion chamber heated to 800°C wherein mercury is converted from a bound state to the atomic state by thermal decomposition in a two-section furnace.
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 sample matrix. Mercury measurements take place in the heated cell zone of converter directly coupled to spectrometer. High temperature (800C) and short residence time prevents Mercury atoms from recombining with any “active” species generated due to high temperature decomposition of sample matrix. External pump is used to draw ambient air and purify it for combustion. No cylinders of oxidizer or compressed gases required. No "clean room" required. Easy to use, maintain and transport.
