Short summary
We investigated a new solid-phase scrubber for use in conventional ozone UV-absorption photometers. A heated graphite scrubber efficiently removed ozone and was less susceptible to interference from water vapor, mercury vapor, and aromatic hydrocarbons compared to conventional metal oxide scrubbers. Reducing interferences from these atmospheric species in conventional ozone photometers could lead to more accurate ozone measurements in compliance monitoring or for indoor air quality.
