One platform, many applications: The power of MAX-iR FTIR gas analysis systems
Thermo Scientific MAX-iR products provide advanced FTIR-based gas analysis, with systems designed for real-time multi-component monitoring in industrial and environmental applications. They help enable simultaneous detection of dozens to hundreds of compounds with high sensitivity—often down to single-digit ppb or even ppt levels—while delivering continuous, automated operation with minimal user intervention. What unifies the array of MAX-iR products is their focus on precision, automation, and versatility across several applications, including process monitoring, emissions compliance, ambient air analysis, and gas purity verification.
Ambient air
Monitor ambient air’s challenging compounds
Measuring challenging compounds like ethylene oxide in ambient air requires technology that minimizes false alarms from interferences and while also meeting EPA and OSHA standards. Effective monitoring demands the ability to detect target compounds at single-digit ppb levels, even in the presence of water, solvents, and hydrocarbons.
Thermo Scientific MAX-iR gas analyzers offer a robust, factory-ready solution for continuous ambient air monitoring. It provides near real-time results across multiple sample points with fully automated operation, zero drift stabilization, and high sensitivity. The MAX-iAQ Ambient Air Monitoring System is designed for ambient air analysis across multiple industries and applications, including indoor environmental health and safety monitoring and cleanroom monitoring. It works well for applications such as medical device sterilization, chemical manufacturing, semiconductor fabrication, and automotive production, and enables reliable 24/7 monitoring with minimal maintenance.
Carbon capture, utilization, and storage (CCUS)
Analyze and monitor changes in the impurity levels of captured carbon dioxide (CO₂)
As organizations advance their decarbonization goals, reliable measurement of CO₂ purity and gas composition becomes increasingly important. Continuous monitoring helps verify carbon stream quality, support transportation and storage requirements, and provide confidence in carbon accounting and reporting programs.
The Thermo Scientific MAX-Bev FTIR Gas Analyzer enables real-time analysis of captured CO₂ streams, delivering the information needed to monitor purity and detect critical impurities. Accurate gas composition data helps protect pipeline infrastructure, support regulatory compliance, and ensure carbon dioxide meets quality specifications for transport and storage.
Ethylene oxide (C₂H₄O)
Monitor and measure ethylene oxide (EtO) emissions at low concentrations
Accurate measurement of EtO emissions is essential for facilities involved in medical device sterilization and chemical production. Our EtO monitoring solutions combine the MAX-iR FTIR Gas Analyzer platform with purpose-built systems for ambient air and stack emissions monitoring, helping facilities identify leaks, understand emissions profiles, and support environmental monitoring and compliance initiatives.
The MAX-iAQ Continuous Ambient Air Monitoring System provides automated, multi-channel monitoring for low-level EtO in ambient air, while the EMS-10 Continuous Emissions Monitoring System supports real-time EtO stack emissions monitoring for compliance with the approved NESHAP Rule. Together, these solutions deliver sensitive, reliable EtO measurement with a detection limit of 1 ppb.
Food & beverage
Help to ensure safety, quality, and compliance in carbonated beverages
Maintaining beverage-grade CO₂ purity is essential for protecting product quality, consumer safety, and regulatory compliance. Continuous monitoring helps beverage producers verify gas quality, identify contaminants such as sulfur compounds and benzene, and ensure carbonation streams meet industry specifications.
The Thermo Scientific MAX-Bev CO₂ Purity Monitoring System delivers fast, reliable analysis of beverage-grade CO₂ and trace impurities. Accurate purity measurements help manufacturers reduce waste, avoid production disruptions, support compliance with International Society of Beverage Technologists (ISBT) and European Industrial Gases Association (EIGA) standards, and protect brand reputation.
Industrial gas
Gas and emissions analysis for industrial process applications
Industrial process applications—from in-process monitoring to final product quality assurance—benefit from the ability of gas analyzers to detect impurities at single-digit ppb levels while delivering real-time, multi-component analysis. For compounds that are not IR-active, complementary technologies such as mass spectrometry or targeted sensors can be integrated to provide a complete solution.
Designed as true system-level solutions, our MAX-iR analyzers go beyond standard rack-mounted setups. They feature advanced multi-channel gas handling, flexible enclosures, and integrated software for seamless communication and automation. Optimized for performance from day one, these systems deliver reliable, high-sensitivity measurements—even in challenging environments—across industries including chemical manufacturing, air separation, semiconductor, and beverage production.
Power generation and data centers
Cleaner, more efficient power generation
As data centers expand to meet growing computing demands, many facilities rely on on-site power generation to support reliability, resilience, and operational continuity. Continuous monitoring of combustion and emissions gases helps operators optimize generator performance, improve fuel efficiency, and support environmental and regulatory objectives.
The Thermo Scientific MAX-iR FTIR Gas Analyzer provides real-time, multi-component analysis of NOₓ, CO, CO₂, SO₂, NH₃, H₂O, and other key gases. Accurate measurement data supports emissions monitoring, RATA validation, combustion optimization, and SCR performance monitoring, helping data center operators maximize power generation efficiency while maintaining regulatory compliance and environmental performance.
Source emissions
Gas and emissions analysis for industrial process applications
Whether you operate a source testing business or need standardized emissions monitoring across global facilities, our MAX-iR monitoring solutions deliver fast, reliable results. This fully automated system eliminates the need for frequent calibrations or liquid nitrogen, while Thermo Scientific StarBoost Enhanced Optical Technology enables single-digit ppb detection of challenging compounds such as formaldehyde and ethylene oxide.
Backed by deep application expertise, these solutions are designed for rapid deployment with support for installation, QA/QC, regulatory compliance, and data validation.
