Thermo Fisher Scientific

A Sensible EDP Collaboration


Montrose has formed a global collaboration with Thermo Fisher Scientific, the world leader in serving science, to provide real time ethylene oxide (EtO) monitoring solutions to meet recently proposed EPA standards.

Montrose and Thermo Fisher have partnered to provide MAX Optically Enhance (OE) FTIR (StarBoost™) continuous monitoring systems. The MAX OE-FTIR is a fully automated 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 the advanced StarBoost™ technology while maintaining short cycle times. It is also designed to operate as a continuous monitor with little-to-no user interaction.

Through this agreement, Montrose and Thermo Scientific will combine the expert field services of Montrose Environmental’s Sensible Environmental Data Platform with Thermo Scientific’s MAX OE- FTIR (StarBoost™) technology to provide Indoor Air Quality monitoring systems (iAQ) and stack Continuous Emissions Monitoring Systems (EMS-10).  These technologies provide various industries the solution to meet recently proposed EPA regulations regarding ethylene oxide.


A Turnkey Solution for Monitoring Ethylene Oxide

The Thermo Scientific iAQ and EMS-10™ Systems, configured with StarBoost Technology, combined with the installation, operations, and maintenance expertise of Sensible EDP™, creates an ideal solution for monitoring low-level EtO emissions from commercial sterilization and chemical manufacturing facilities. With an LOD of 1 ppb and responsivities of less than 15 seconds, the iAQ and EMS-10 OE-FTIR systems show superior performance compared to standard GC systems, which typically have an LOD of 50 ppb and an analysis time of minutes.

Using a technology with lower detection limits prevents the over-reporting of emissions when stack concentrations are below 50 ppb. Not only does the performance of the iAQ and EMS-10 OE-FTIR systems exceed the US EPA standards for EtO, but the system’s flexibility and sensitivity make it easier to adapt to shifting regulations, such as the proposed changes to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for sterilization facilities and chemical plants (40 CFR Part 63) as well as the Proposed Interim Decision (PID) for sterilization facilities. 

The EPA has recently issued 3 focused proposals addressing the reduction of EtO Emissions from chemical plants and commercial sterilizers, and reducing risk to workers in the sterilization industry. This groundbreaking partnership brings a turnkey solution to market, meeting the needs of industry to monitor EtO at extremely low levels. Our combined solution offers best in class technology and field expertise to meet the increasing standards and regulations issued by the EPA.
