High Precision
The Thermo Scientific IRIS 4100 Mid-IR
Laser-Based CO2 Analyzer uses
state-of-the-art mid-infrared laser absorption
spectroscopy to measure carbon dioxide. The
IRIS 4100 analyzer is capable of providing
continuous, real-time measurements that are
highly precise and accurate.

Advanced Laser Technology
Using our unique Difference Frequency
Generation (DFG) technology, the
IRIS 4800 analyzer is capable of providing
measurements in the middle-infrared
spectral region. DFG technology is based
on the principle of two telecom laser
sources that are combined into a single
optical fiber. The combined lasers are then
focused into a “non-linear” Periodically
Poled Lithium Niobate (PPLN) crystal. The
signal is then transferred through an
optical cell.

The laser, located within the optical cell of
the IRIS 4100 analyzer, is approximately
100 times narrower in frequency than the
intrinsic absorption line-width and sweeps
continuously through the associated lines at
a repetition rate of 500 Hz. The single pass
within the cell reduces the risk for mirror
contamination and simplifies maintenance
requirements.

Single box solution
This single box solution, featuring an internal
pump, is designed for continuous operation
and can be used in conjunction with
external sampling interfaces. In addition,
the IRIS 4100 analyzer provides numerous
diagnostic monitoring features such as
temperature, pressure, and line strength.
It also includes web-based remote access
to enable continuous monitoring of system
performance and health in the field.
