Ethylene Oxide Monitoring

Sensible EDP Solutions

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.

Montrose has formed a global collaboration with Thermo Fisher Scientific, the world leader in serving science, to provide real time ethylene oxide monitoring solutions which meet the requirements of various regulations. Montrose and Thermo Fisher Scientific have partnered to provide the continuous monitoring systems for indoor air quality and stack emissions.

 

 

MAX-iAQTM 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 below 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-10TM FTIR Continuous Emissions 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 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.

 

Planning for Upcoming Ethylene Oxide Requirements

On April 11, 2023, the U.S. Environmental Protection Agency (EPA) issued a Proposed Interim Decision (PID) intended to reduce the risk regarding the use of ethylene oxide for all workers and others that work or live near sterilization facilities. As part of the revised regulation, facilities would be required to monitor indoor air with an action threshold of 10 ppb.  More information on the PID can be found here.

Also, on April 11, 2023, the U.S. EPA proposed to modify the National Emission Standards for Hazardous Air Pollutants (NESHAP) for ethylene oxide emitted into the air from commercial sterilizers. As part of the revised regulation, facilities would likely have to monitor stack emissions at low, sub ppm levels.

And on April 6, 2023, EPA announced a proposal to modify the air toxics rule for Hazardous Organic NESHAP, often called the "HON" The proposal is intended to significantly reduce emissions of ethylene oxide (EtO) from Synthetic Organic Chemical Plants and Group I & II polymers and resins plants.
