Achieving effective EtO abatement in problem areas like office spaces and laboratories on discrete HVAC circuits, and warehouse areas with freestanding finished goods, has been particularly challenging. This white paper discusses the performance of a new, low-power, photocatalyst-based technology for abating EtO in these settings—Sonata Scientific’s Helios^TM EtO control technology platform—with performance validated using the demonstrated capabilities of Picarro’s EtO Workplace Monitoring System (WMS).
