QS9000 TDL GAS ANALYZER
QS9000 TDL GAS ANALYZER
The QS9000 is a laser based in-situ gas analyzer which measures the concentration of flue gases in a cross-duct configuration using the Tunable Diode Laser Absorption Spectroscopy (TDLAS) technique. This technique delivers highly accurate and reliable data which is not affected by the background gases and environmental conditions. QS9000 performs measurements in a non-contact manner and is suitable for measurement of corrosive gases in harsh process conditions.

QS9000 is installed directly on the stack and no sampling is required, therefore, a response time as fast a <1 second can be reached.
Because the diode lasers can resolve single absorption lines of the gaseous molecules, the measurements are highly selective and insensitive to interference from background gases.
Wavelength Modulation Spectroscopy (WMS) and Digital Signal Processing (DSP) techniques make QS9000 extremely accurate and reliable even in high temperatures, high pressures, dusty environments and harsh process conditions.
The laser source and the photodetector are isolated from the flue gas; this prevents them from being contaminated. The non-contact nature of the QS9000 makes it suitable for measurements in the presence of corrosive gases.
No/Low Zero Drift
The diode lasers used in QS9000 are telecommunication grade lasers which are very stable and provide a virtually drift-free technology.
No sampling or conditioning equipment it required. The only maintenance required is annual calibration and periodic optics cleaning.
Low Cost of Ownership
Below features make QS9000 laser analyzers to have lower cost of ownership compared to other gas analyzers:
– long-term calibration free operation,
– long lifetime components,
– low maintenance,
– no consumables,
– easy installation.
Diode lasers used in QS9000 analyzers have long operational lifetimes (typical MTBF of 15 years).
