Ohio Lumex provides a complete, turnkey approach to landfill gas (LFG) and Renewable Natural Gas (RNG) analysis, supporting projects from initial sampling through laboratory analysis and continuous monitoring. Rather than relying on multiple vendors for sampling, testing, and monitoring equipment, Ohio Lumex provides integrated solutions designed specifically for the biogas and RNG industry, tailored to each landfill project.
Ohio Lumex provides analytical instruments, monitoring systems, and sampling solutions for landfill gas measurement applications. Our solutions support gas composition monitoring, siloxane measurement, mercury monitoring, and landfill gas upgrading projects.
On-site sampling for landfill gas (LFG) and Renewable Natural Gas (RNG) is performed by certified field service technicians per approved methods for compliance with pipeline RNG gas quality specifications, the EPA Renewable Fuel Standard (EPA RFS), qualification for 45Z Production Tax Credits (PTC) via ASTM D8080, process control, and upgrading equipment specification.
Ohio Lumex will provide all equipment, supplies, and instructions to sample per the approved methods for compliance with pipeline RNG gas quality specifications, the EPA Renewable Fuel Standard (EPA RFS), qualification for 45Z Production Tax Credits (PTC) via ASTM D8080, including appropriate return shipping cartons and labeling to comply with DOT requirements. Ohio Lumex offers options for RNG sampling classes at our headquarters and onsite.
Our analytical laboratory supports detailed characterization of gaseous fuels samples, helping clients understand gas composition and identify trace constituents that impact performance and compliance.
We support analysis for:
Sampling and analysis is complex, and improper handling can impact data accuracy, making experienced laboratory support critical to reliable results.
Every landfill project is different, and as a leader in biogas and RNG analysis, our experience in continuous monitoring, onsite sampling, and laboratory analysis helps deliver accurate and reliable data that all parties trust.
Landfill gas can introduce elevated concentrations of trace constituents that must be removed to meet gas quality requirements. Older landfill wells may introduce mercury from discarded items such as thermometers and light bulbs, while newer waste streams often introduce higher levels of siloxanes from plastics, cosmetics, shampoos, soaps, and other silicon-based products. Landfill gas may also contain toxic metals such as arsenic, antimony, copper, and lead, as well as PCBs, which require careful monitoring and analysis.
Accurate dry gas volume calculations are essential for defensible sampling and regulatory compliance. As part of our commitment to precision, we developed an automated Dry Gas Volume Calculator to simplify corrections and ensure consistent results for biogas, RNG, and gaseous fuels applications.
In addition to field services and laboratory analysis, we provide biogas and RNG training courses designed to support compliance, proper sampling techniques, and gas quality best practices. These sessions reinforce industry standards and have helped operators improve performance and reduce costly errors.
Many gaseous fuel testing programs rely on sorbent trap sampling methods to measure trace contaminants in natural gas, renewable natural gas (RNG), biogas, and other fuel streams. A sorbent trap is a small glass tube filled with specialized sorbent material that captures specific compounds as gas passes through it. After sampling, the traps are returned to a laboratory for analysis.
Sorbent traps are commonly used to measure mercury, sulfur compounds, siloxanes, and other trace constituents that can impact fuel quality, equipment performance, and downstream processing. These methods provide reliable results at very low concentrations while offering a practical and cost-effective approach for many gaseous fuels applications.
