Real-Time Ethylene Oxide Monitoring

Montrose Environmental is here to support your organization with continuous monitoring of ethylene oxide (EtO). We offer integrated, proven, and easy to deploy solutions, which deliver low detection limits to serve your project applications. Our ethylene oxide monitoring solution has been installed and operating for years supporting stack and indoor air quality monitoring programs. Our clients benefit from the credibility and trust we have garnered in this field, but also from our consistent and continued commitment to enhance our capabilities in this transformative space.

Ethylene oxide is a widely utilized sterilizing agent for medical equipment and devices and has been increasingly scrutinized due to its potential negative health effects, such as carcinogenicity and mutagenicity. As a result, federal, state, and local agencies have implemented stricter regulations surrounding EtO emissions, including the Proposed Interim Decision (PID) intended to reduce the risk to workers regarding the use of ethylene oxide and the proposed National Emission Standards for Hazardous Air Pollutants (NESHAP). Companies operating in this space must stay informed about these regulatory changes and adapt their practices accordingly to ensure compliance and minimize risks.

Thermo Fisher Partner

Global Collaboration with Thermo Fisher Scientific

Montrose Environmental Group and Thermo Fisher Scientific have collaborated to provide an all-encompassing solution for organizations facing challenges in EtO emissions monitoring, testing, and regulatory compliance. By integrating Montrose’s extensive project services expertise with Thermo Fisher's cutting-edge StarBoostTM Optically Enhanced MAX-iAQ™ OE-FTIR Gas Analyzer, clients gain access to a powerful combination that streamlines their efforts to meet stringent regulations and maintain safe operations.

MAX-iAQ™ OE-FTIR Continuous Monitoring System

The MAX-iAQTM is a fully automated 20-channel ambient air monitoring solution for low-level detection of EtO, even in high humidity environments. It can quantify EtO to a detection limit of 1 ppb using advanced StarBoost™ technology while maintaining short cycle times. It is also designed to operate as a continuous monitor with little-to-no user interaction.

MAX-EMS-10™ OE-FTIR Continuous Monitoring System

The EMS-10™ Continuous Emissions Monitoring System (CEMS) is a fully automated 4-channel stack emission monitoring system designed specifically for hot wet samples. The EMS-10 system can quantify ethylene oxide down to a detection limit of compounds down to a detection limit of 1 ppb while maintaining short cycle times, using advanced OE-FTIR spectral analysis and Thermo Scientific™ StarBoost™ Technology. This makes the EMS-10 an ideal alternative to traditional gas chromatograph-based systems that are typically slower, less sensitive, and more costly to maintain.
