Ohio Lumex - Model M324 -Sorbent Trap Mercury Analyzer

• Analyze samples from 0.2ng/g (0.2ppb) to 30,000,000ng/g (30,000ppm)
• Most analyses take 90 seconds. Very high level samples take only 8-11 minutes
• Sample Sizes up to 5g
• Versatile: analyze aqueous samples thermally down to 5ug/L with no digestion
• Analyzer module is the finest Hg vapor monitor available, able to detect < 2 ng/m3
• No catalyst, gold amalgam, or drying tube, hence the analyzer is not prone to damage from high-level or halogen contaminated samples

• Capital and operating costs a fraction of CEMMs costs
• Mature proven technology, reliability proven by many systems in use
• Simple, dependable, easy and inexpensive to maintain
• The only system capable of reliably measuring low levels (<0.5 micrograms per cubic meter.) This will be critical where Mercury Reduction is mandated

• Can be used as a low cost back-up system during CEMMs maintenance and repair where a loss of data can mean tens of thousands of dollars
• Check the accuracy of your calibrators
• Perform your own RATA and pre-Rata tests
• Excellent CEMMs trouble-shooting tool
• Perform Speciation Studies using our Ohio Lumex Speciation Traps
• Flexible for testing at different points and assessing Mercury Reduction Schemes
• Can be used to determine mercury levels in coal, ash, and other materials
• Perfect to reveal best optimization of Sorbent Injection Systems

• Much simpler to perform than Method-29 or “Ontario Hydro” method
• Results in minutes
• Quickly categorize source levels on site
• Only collect the number of samples needed (9 versus 12 runs) - no need to collect extra runs to assure 9 good results
• Finish RATA using method compliant results before leaving the site
• Saves money compared to other methods or off-site analysis
• “One-Shot” argument: both Digestion and Thermal Methods are destructive if sample is lost on Trap Disassembly. The penalty for on-site Thermal Analysis is merely another run

Ohio Lumex analyzer on site:

• Typical RATA in 1.5 - 2 days
• Minumal runs required (as few as 9) since data integrity can be determined on site
• Testing team has to complete control over analysis

Ontario Hydro method:

• 3 - 5 days required to get 12 runs
• Results analyzed off-site
• Testing must be repeated if 4 or more runs fail
• Equipment is expensive and fragile

Sorbent traps analyzed off-site:

• Must do extra runs to ensure 9 good runs (12 vs. 9)
• Retesting required if 4 or more runs prove to be bad
• Impossibe to predict spike value for Field Recovery Test

Using CEMM as an instrumental reference method:

• Expensive
• Dynamic spiking is complicated to perform
• No portable NIST Traceable Calibrator for "total" Hg is commercially available
• Wet stacks and high particulates can cause problems
