GasEye tunable laser Mid – IR multi component TLS spectrometer
GasEye tunable laser analyzer is a multi-component gas analyzer. It can be
configured for applications in the NIR, mid-IR and IR wavelength range
The measurement technology behind the GasEye allows for sensitive and selective
measurements of gas concentration down to single ppb levels. The technology allows for
real-time in-line measurements with a response time down to 0.1 second depending on
application. The analyzer is mid-IR ready and the first to integrate interband cascade laser
(ICL) technology. Airoptic has a long tradition in laser spectrometer design for industrial
applications. The GasEye tunable laser gas analyzer is equipped with a self calibrating
feature, making it maintenance free. The analyzer is insensitive to dust, smoke,
temperature variations and optics contamination providing reliable measurements in harsh
environment.
Features;

Real time sensing – response time below
0,5 second

High selectivity – sensitive and selective
measurements of gas concentration
down to single ppb levels in a complex
background gas matrix.

GasEye tunable laser is manufactured in
three different variants;
o Long-Path for In-situ monitoring
– reliable and representative
area measurements
o Cross-duct for in-line process
monitoring and control
Applications;

Engine exhaust gas analysis

Process monitoring and control in
the Hydrocarbon and Chemical
industry

Trace components in natural gas;
e.g. H2O, CO2, H2S

