SSN-2024-034-JS - Picarro G2307 Cavity Ringdown Spectrometer for HCHO, CH4, and H2O

The Department of Atmospheric Science at Colorado State University intends to purchase a Picarro G2307 Cavity Ringdown Spectrometer for HCHO, CH4, and H2O concentration analyzer system that includes field deployable capabilities via sole source. The instrument will assist CSU with trace gas measurements of formaldehyde at parts-per-billion (ppb) to sub-ppb levels and methane at low parts per million levels in air. This instrument will help CSU make direct high time resolution measurements of formaldehyde to better characterize its impacts on human respiratory health and formation of ground-level ozone and methane to help assess contributing emission sources. These are pressing air quality challenges across the nation, including here on the Colorado Front Range where there is increasing attention on exposure to air toxics and Colorado has been classified by USEPA as a severe nonattainment area for ozone.
