Air monitoring technology for ethylene oxide (EtO)


New measurement technology that can identify and quantify EtO emissions over a broad range, inclusive of levels at or below concentrations indicative of long-term risk at the 10-4 risk (0.02 ug/m3, or nominally 12ppt), allow for needed ambient, near source and source testing. Additionally, new technology must be able to distinguish EtO from potential interfering compounds, including but not limited to trans-2-butene or acetaldehyde, that can be confounding across a variety of analyses. Ideally, new technology would provide continuous, real-time online measurements, with a seconds to minutes sampling rate.
