The LaserGas™ Q ICL is an in-situ gas analyzer for continuous measurement of NO, NO₂, SO₂ and other mid-infrared species.
It uses interband and quantum cascade lasers to achieve low detection limits. These mid-IR wavelengths allow the analyzer to measure gases that near-IR TDL systems cannot detect reliably.
The LaserGas Q ICL installs directly across the process duct. It removes the need for extractive sampling or long heated lines. A continuous purge protects the optical windows and keeps the signal stable in dusty or high-temperature conditions.
Key Features:
- Mid-infrared TDL spectroscopy (ICL/QCL)
- Fast response, down to 1 second
- Measures NO, NO₂, SO₂, HBr, CH₂O
- No extractive sampling required
- Purge-protected optics
- Stable calibration, no zero drift
- CSA Class I/Div 2 and ATEX/IECEx Zone 2
Suitable for:
Combustion control, DeNOx, SRU gas-side monitoring, sulphuric acid plants, and CEMS.
