The EPA’s Subpart-O NESHAP for Ethylene Oxide (EtO) in commercial sterilizer facilities mandates up to 99.99% destruction removal efficiency (DRE) for abatement systems. For sterilizers, abatement plant manufacturers, and catalyst providers, proving compliance with this level of DRE has historically been difficult because of the sensitivity limits of legacy monitoring technologies. That’s why, when Carus wanted to prove the DRE of their catalyst product, they partnered with Picarro. Leveraging its advanced technology and extensive expertise in EtO monitoring and regulatory compliance, Picarro was able to provide Carus with the data they needed to prove CARULITE®500 achieves 99.99988% DRE – exceeding EPA requirements.
