In 2023, a leading medical device sterilization facility found itself on shaky ground. Emissions compliance was managed through a patchwork of manual recordkeeping and periodic testing, with limited real-time insight using their existing monitoring systems. The company was prepared to pour eight figures into new oxidizers and dry scrubbers, not because their existing abatement system couldn’t destroy the ethylene oxide (EtO) gas, but because they couldn’t prove it. 

Instead, they turned to Picarro, whose next-generation monitoring systems had a proven track record of delivering repeatable sub-ppb EtO measurements without interference. Leveraging Picarro’s turn-key solution, the site had a working implementation of a CEMS within 1 week, reporting near 100% DRE with existing abatement, and passing daily calibrations at 10 ppb consistently. Beyond providing high data integrity, Picarro’s integrated approach came with a built-in compliance logic that automatically tracked abatement temperatures, flow rates, EtO throughput, and other critical process parameters. Equally significant, Picarro offered an end-to-end service model, handling every aspect of the facility’s emissions management program—from certification testing and maintenance, to regulatory reporting—thus removing the burden of fragmented services and compliance cost management. 

As a result, the sterilization company gained one source of truth for real-time process efficiency data, saved millions on unnecessary abatement upgrades, reduced operational risk from public and regulatory intervention, and shifted focus back to its core mission of delivering safe, sterile medical devices.
