CRDS proven as leap in measurement and monitoring to support accurate exposure data
Santa Clara, CA – July 20, 2020 – CleanAir Engineering (CleanAir) has completed a feasibility study on the measurement of Ethylene Oxide (EtO) using the Picarro G2910 EtO Gas Concentration Analyzer, by measuring this hazardous air pollutant in real-time at detection limits of parts-per-trillion (ppt) from a stack. While the mutagenic properties of EtO have been known since the 1940s, the regulatory landscape around emissions and exposure limits has evolved over time. Today, while it is an important chemical used for the sterilization of medical equipment, it is now believed to be more harmful than previously realized. A leap in analytical instrumentation was required to better characterize the risk to workers and communities.
In the feasibility study, CleanAir performed comparative measurements applying the G2910 EtO analyzer to a variety of process streams in a sterilization facility including dry scrubbers, wet scrubbers, and thermal oxidizers, as well as monitoring fugitive emissions and leaks in and around a chemical plant. According to Dr. Volker Schmid, Technical Leader of CleanAir’s Advanced Monitoring Solutions Group, “Picarro’s measurement technology allows CleanAir’s clients to make informed decisions based on reliable rapid EtO measurements at extremely low levels.”
Picarro analyzers enable the industry, services providers, regulators, and researchers access to accurate and effortless measurements of EtO, thus minimizing and preventing exposure of humans and the environment to this toxic gas.
The EtO family of analyzers represents a monumental advancement in measurement and monitoring technology and is realized by a refinement of Picarro’s existing Cavity Ring-Down Spectroscopy (CRDS) platform. The technology is able to rapidly resolve complex spectral signatures at limits of detection (LOD) that are orders of magnitude lower than those achieved by traditional methods based on Fourier Transform Infrared (FTIR) spectroscopy and Gas Chromatography (GC). The remarkable stability, performance, and ease-of-use of the platform, adopted over the years by the world’s most demanding research organizations, now provides an exciting alternative to a market in desperate need of disruptive technology.
“We thank CleanAir for their efforts to prove this solution compared to existing technologies and showing that it provides previously unavailable insight” said Joel Avrunin, VP of Scientific Instrumentation for Picarro. “We look forward to furthering the knowledge of how EtO disperses and persists in the environment to assist our communities and industry partners in this important task.”
