The UW-Air Quality Research Group's Mobile Air Quality Monitoring Laboratory (MAQML) facility is equipped with EPA method gaseous pollutant analyzers as well as meteorological monitoring. We are configured to continuously measure ozone (O3); nitric oxide (NO), nitrogen dioxide (NO2), and oxides of nitrogen (NOx); methane (CH4), and non-methane hydrocarbons (NMHC); and carbon monoxide (CO) according to EPA approved methods. The laboratory is configured with a custom Data Acquisition System that allows for remote observation and collection of data.

Thermo Scientific Model 48i-TLE Analyzer: Gas filter correlation and NDIR analyzer measure trace levels of carbon monoxide (CO) in ambient air. Sample conditioned temperature stabilization and auto-zeroing result in a low detection limit for the measurement of Carbon Monoxide which is regulated as a proxy for organic HAPs like formaldehyde.
