Ambient Gas Monitoring

We offer a variety of analyzers for the ambient monitoring of the criteria pollutant gases, including CO, NOX, SO2, and others such as CH4 and CO2.

Nitrogen and Nitrous Oxide (NO-NO2-NOx-NOY-N2O) Monitoring

Measure nitrogen oxides (NO-NO2-NOx) in the emissions from a source, including nitrogen oxides in the air from sub-ppb levels up to 100ppm.

NOx Analyzer

Sulfur Dioxide (SO2) Monitoring

Measure the levels of SO2 in ambient air down to 50ppt or measure high levels of SO2 from a source up to 10,000ppt.

SO2 Analyzer

Carbon Monoxide (CO) Monitoring

Measure a broad range of CO—from high levels of CO emission to trace levels in ambient air.

CO Analyzer

Ozone Monitoring

Measure the amount of ozone in ambient air with the dual-cell, UV photometric Thermo Scientific™ Model 49i Ozone Analyzer.

Ozone Analyzer

Methane and Non-Methane Hydrocarbons Monitoring

Make automated measurements of methane and non-methane hydrocarbons with the Thermo Scientific™ Direct Methane & Non-Methane Hydrocarbon Analyzer.

Direct Methane

Ammonia (NH3) Monitoring

Measure ammonia (NH3) concentrations in ambient air with the Thermo Scientific™ Ammonia Analyzer.

Ammonia Analyzer

Zero Air

We offer systems for the reliable removal of carbon monoxide and hydrocarbons from filtered ambient air, as well as systems that generate ultra high purity zero air for analytical and process instrument needs.
