Ohio Lumex IRM 915
Portable Mercury CEM
• Suitability: Designed to perform Parametric Hg Testing, Hg Control Technology
Evaluation, and Baseline Studies on site. Can be used for the Inlet (after boiler) as well as
for the Outlet (stack) long and short term applications.
• Portability: set-up and dismantling time ~2-3 hours. Low power and footprint
requirements.
• Wide range: 0.1-100 ug/m³
• Speciates: Hg0 and Hg2+
• Modular design for component “swap” in the field.
• Reliability: Performance is proven through Sorbent Traps which are run to confirm the
CEMs daily.
KEY FEATURES:
• Spectrometer: The IRM
915 features a highly
sensitive atomic
absorption
spectrometer with
Zeeman background
correction providing
interference free
measurements.
• The Probe/Filter: Hasteloy heated
probe (18 months in wet stacks)
• Multiple Dilution ratios.
• Sampling is based on high velocity
extraction, filtering, and dilution.
No mechanical pumps are used and
are instead replaced by plant air.
• Critical orifice provides precise
sample dilution.
• The probe and filter are selfcleaning based on periodical
blowback eliminating the “reactive
ash” Hg scrubbing effect.
• Speciation: provided by
bypassing converter
and measuring
Elemental Hg only.
• Calibration: Built in
Elemental Hg calibrator
with low span (2-5
ug/m³). No other
calibration source
required.
• Umbilical Lines: Heated
line from 10ft to 30ft
(others available).
• Data Results: Recorded via a
control system computer and
saved in a csv formatted file.
With internet access, on-line
remote data transfer and
analyzer control/calibration
capabilities.
• Utilities Requirements:
Power: 3 110 or 220 volt lines set
for 15 or 20 amp Breakers, 2000
watts Total.
Compressed air (dry, -40°C), 1
SCFM at 80 PSIG or plant air at 2

Ohio-Lumex Analyzer
ANALYZER TECHNOLOGY
Lumex-RA915+ with RP-M 324 is designed for field/ on-site or laboratory “Direct” testing of
carbon sorbent traps for Monitoring of Hg emissions from coal-fired power plants.
Analyzer accuracy is US EPA validated and based on thermal decomposition combined with Zeeman Atomic Absorption
Spectrometry.
No sample preparation is required for analysis. Analysis time is less than 2 minutes per sample.
No chemicals or gases required, no chemical waste is generated.
It is the only high sensitivity and selectivity instrument that does not require gold amalgam and catalyst for analysis.
Analyzer can be used for “Direct” testing of ash, coal and “Ontario Hydro” method generated liquid samples.
Multi-point calibration protocol conforms to EPA Performance Based Criteria Method.
No “Clean Room” is required.
There are no interferences.
Accurate results for “WET” and “DRY” stacks validated in many studies.
Easy to use and maintain, field portable and rugged
TECHNICAL SPECIFICATIONS
1.Detection limit: 0.3ng-100,000ng, mercury, or 10ug/kg-200mg/kg Hg concentration in sorbent, fly ash, coal, liquid
“Ontario Hydro” impinger samples.
2.Direct analysis (results in two minutes) for “small” and “large” sorbent traps.
3.Calibration: NIST Standard on sorbent.
4.Set-up or take down time: less than one hour.
5.Dimensions and weight: Two Rolling Pelican Cases, Total 110 lb.

SPECIATION TRAPS
● 2 types of sorbent
● Separately capture oxidized and elemental Hg.
● Made with Extra durable thick glass for rugged field use.
● Standard for moisture resistance.
● Acid Gas Scrubbers built in.
● Can be spiked.
● Used in “Wet”, “Dry”, and high particulate sources.
● We will always consult you on how best to conduct your testing for the most optimal and
accurate results.
● Extensively Field Tested!
PLEASE KEEP IN MIND
● Temperature (May need to use a cooling probe)
● Flow
● Sample Duration
SORBENT TRAP Hg MONITORING TECHNOLOGY
Ohio Lumex Sorbent Traps conform to PS-12B or Appendix K sampling and analysis specifications.
A specific concentration of Iodine deposited on acid washed activated carbon ensure extreme mercury
capturing capacities without “Break through” for extended test periods in “wet” or “dry” stack
emissions from coal-fired power plants.
PLEASE NOTE: High Iodine is a major interference in alternative method 1631 analysis and requires our
competition to limit iodine concentration on carbon resulting in higher potential for breakthrough and low
“spike” recoveries.
Specifications:
1. Low Mercury “background” level less then 0.3 ng per section.
2. High Sorption capacity up to 2,500,000ng.
3. Long term storage stability in provided container.
4. Unique numbering with high temperature ink and “chain of custody.”
5. Easy On/Off “leak check” cap plugs.
6. Third section is pre-spiked with elemental Hg at customized level.
