About Ohio Lumex

Ohio Lumex Co., Inc. is a Northeast Ohio analytical technology company that measures difficult analytes, above all mercury, at trace levels. Founded in 1999, when it introduced the RA-915 Zeeman mercury analyzer to the US market, it now combines instruments, sorbent traps, an accredited laboratory and field testing under one roof.

Headquartered in Solon, Ohio, the company serves electric utilities, cement plants, incinerators, gas producers and research labs across North America. In February 2026 it launched an Integrated Technology Solutions (ITS) division in Valparaiso, Indiana, for PLC/SCADA integration, control panels and commissioning.

What Ohio Lumex makes

Mercury measurement remains the core of the business. For stacks and process gas, the 915J continuous mercury monitor is built for coal-fired boilers, cement kilns and incinerators. Portable RA-915M analyzers handle spill response and exposure checks, and laboratory systems such as the M324 analyze sorbent traps with minimal sample preparation.

The Elemental Instruments brand, launched in 2020, extends the company into gas quality. The Ei800 process GC and Ei2200 RNG monitoring system report composition, heating value and siloxanes for renewable natural gas and biogas projects, while the Ei4200 measures actual acid dew point rather than estimating it. Ohio Lumex is also the exclusive North American distributor for G.A.S. GC-IMS instruments and distributes PyroScience optical oxygen, pH and temperature sensors in the US and Canada.

Why engineers specify Ohio Lumex

  • One accountable source. A plant can buy the monitor, the Method 30B traps, third-party lab analysis and RATA field support from the same company.
  • Proven measurement physics. Zeeman atomic absorption with a multi-pass cell reads mercury directly, even with SO2, moisture or organics present.
  • Accredited laboratory. The lab holds ISO/IEC 17025:2017 accreditation through A2LA and NELAP accreditation, along with state programs including Louisiana and Virginia.
  • Regulatory fluency. Products and services support EPA Method 30B, Performance Specification 12B, MATS mercury monitoring and Renewable Fuel Standard gas-quality compliance.
  • Flexible ownership. Rental and lease programs suit short studies and pre-purchase evaluations.

Local support from Vaughn Associates

Southeast facilities face a mix of mercury and gas-quality requirements, from power producers and cement plants to pulp mills, landfills and farm digesters. Vaughn Associates helps sort out which Ohio Lumex approach fits best: a continuous monitor, a sorbent trap program, contracted testing or a combination.

Our engineers review the application, gather stack or gas-stream details, coordinate quotes and technical questions with the factory, and stay involved through delivery and beyond. Ohio Lumex is covered in every Vaughn territory, with North Carolina the only covered state in our North Carolina, Virginia, Maryland and D.C. territory.

FAQ

Common questions about Ohio Lumex

Who represents Ohio Lumex in the Southeast?

Vaughn Associates, Inc., an independent manufacturer's representative headquartered in Huntsville, Alabama, with an office in Baton Rouge, Louisiana, represents Ohio Lumex across its Southeast territories. In the North Carolina, Virginia, Maryland and D.C. territory, coverage is North Carolina only. Vaughn's engineers help plants review mercury and gas-quality applications, coordinate quotes with the factory and stay involved after the order is placed.

Is Ohio Lumex the same company as Lumex Instruments?

No. Ohio Lumex Co., Inc. is a separate US company founded in 1999 near Cleveland, Ohio, which introduced the RA-915 Zeeman mercury analyzer to the US market that year. Lumex Instruments, which developed the RA-915 platform, is headquartered overseas and lists Ohio Lumex as its distributor for the United States and Canada. Ohio Lumex also designs its own Elemental Instruments products and runs its own accredited laboratory.

How does Zeeman background correction improve mercury measurement?

Zeeman correction applies a magnetic field that splits the mercury absorption line, letting the analyzer separate true mercury absorption from broadband interference caused by SO2, organics, moisture or particulates. Combined with a multi-pass optical cell, it allows direct trace-level mercury measurement without gold amalgamation or heavy sample preparation, which matters in flue gas, natural gas and other complex sample matrices.

What does Ohio Lumex offer for EPA Method 30B and PS-12B compliance?

Ohio Lumex covers the full sorbent trap process. It supplies Method 30B and PS-12B sorbent traps, the OLM30B sampling system for collecting samples, and the M324 analyzer for in-house trap analysis. Its accredited laboratory can analyze traps as a third party, and its field engineers perform onsite analysis for mercury monitor RATAs. Plants can buy equipment, contract the testing, or combine both.

Can Ohio Lumex monitor RNG and biogas quality for pipeline injection?

Yes. The Ei2200 RNG Monitoring System combines the Ei800 process GC with GC-IMS siloxane measurement to report gas composition, heating value, relative density and speciated siloxanes, and it is designed to support Renewable Fuel Standard compliance. A Class I Div 2 configuration is available. Ohio Lumex also offers onsite gas-quality sampling and laboratory analysis against pipeline gas-quality specifications.
