The Applied Analytics #OMA is the ideal multi-component instrument for analyzing true NO_X (NO + NO₂) in emissions and critical process applications.

The release of nitrogen oxides (NO_X) to the atmosphere causes the formation of nitric acid rain and depletes the ozone layer. These emissions are heavily regulated around the world. Industrial combustion sites must report the amount of NO_X exiting their stack and often implement processes like DeNO_X to reduce these emissions.

• Continuously measures true NO_X concentration by monitoring NO and NO2 absorbance curves
• Totally solid state build with no moving parts — modern design for low maintenance
• Affordable alternative to large CEMS investments
• Optional close-coupled installation provides faster response than extraction at less cost than cross-stack

Applications

The release of nitrogen oxides (NOx) to the atmosphere causes the formation of nitric acid rain and depletes the ozone layer. These emissions are heavily regulated around the world. Industrial combustion sites must report the amount of NOx exiting their stack and often implement processes like DeNOx to reduce these emissions.

Proven Applications

• continuous emissions monitoring systems (CEMS)
• DeNO_X
• selective catalytic reduction (SCR)
• selective non-catalytic reduction (SNCR)
• diesel engine exhaust
• flue gas
• stack gas

NOX Absorbance Spectra

To measure true NOX, the OMA individually measures NO and NO2 concentrations. The powerful multi-component software isolates the distinctive absorbance curves of the analytes and mathematically isolates their structures from the total sample absorbance. In accordance with Beer-Lambert Law, the OMA correlates the height of these curves directly to real-time concentrations. The NOX reading is a simple sum of the two measurements.

Sampling

The OMA is built for direct analysis of the hot/wet sample, thus simplifying the scope of the sample system and retaining high sample integrity. From our vast experience in sampling design, we know that applications can be similar but are rarely identical. For this reason, we design and build sample conditioning systems on a project basis, working from the process to the drawing board.
