Explore IndustriesBy Technology
Compare TDLAS and related analyzer routes for your process.
Explore TechnologySolving Real Process Challenges
We design gas analysis solutions around specific process conditions — not generic industry categories.
Combustion Control & Optimization
O₂ and CO measurement at boiler, furnace, and heater outlets for fuel efficiency and excess air control.
CEMS Compliance (EPA / EN 14181)
Continuous stack gas monitoring for SO₂, NOₓ, CO, CO₂, and O₂ to meet emission regulations.
SRU / Claus Tail Gas Monitoring
H₂S, SO₂, and COS analysis in sulfur recovery units for process optimization and environmental compliance.
Inerting & O₂ Safety
Oxygen monitoring in nitrogen-blanketed vessels, silos, and reactors for explosion prevention.
Biogas Quality & Upgrading
CH₄, CO₂, and H₂S measurement in anaerobic digester gas, landfill gas, and biogas upgrading systems.
Fugitive Emission Detection (LDAR)
VOC detection and leak monitoring per EPA Method 21 for refineries, chemical plants, and storage facilities.
