2 Theory of Operation
Topics covered in this chapter:
• Overview
• Quantum Cascade Laser
• Measurement process
2.1 Overview
The CT5100 CGA is a gas sensor system that can be configured to measure the
concentrations of multiple small molecules carried in the gas sample. The types of
molecules that are measured depend on the system configuration.
The CT5100 CGA can be configured to detect and measure up to ten gases, with ranges
varying from parts per million (ppm) to percent (%) levels. A detailed description of the
system is given in Chapter 3 of this manual.
Theory of Operation
2.2 Quantum Cascade Laser
The CT5100 CGA uses up to six Quantum Cascade Lasers to detect and measure the gases.
Each QCL measures between one and three gases.
Inside the QCL, which is about the size of a pin head, electrons cascade down a series of
quantum wells, producing a photon at each step. This cascade of electrons can produce
between 20 and 100 photons per electron, giving QCLs higher output power than
traditional semi-conductor lasers.
The lasing wavelength of a QCL is determined by adjusting the physical thickness of the
semiconductor layers, giving access to high power lasers covering the mid-infrared
spectral region. A QCL has no need for cryogenic cooling, has excellent spectral quality in
chirped mode, and good tunability.
2.3 Measurement process
In the CT5100 CGA, gas concentrations are measured using mid-infrared optical
absorption spectroscopy. The light sources are QCLs, which are operated to produce
wavelength sweeps that cover the absorption lines of the gases to be measured.
Sample gas, which may contain impurity gases that are to be detected and measured, is
conditioned and drawn into the CT5100 CGA. Inside the CT5100 CGA, the sample gas is
fed into an analysis cell, where the beams from the QCLs are passed through the gas. The
analysis cell contains a set of mirrors that bounce the light back and forth many times,
Operations Manual 3
Theory of Operation
which lengthens the path of the lasers through the gas. On exiting the analysis cell, the
light is detected by a receiver unit. The variation in the intensity of light in the vicinity of
absorption lines for the gases being detected is measured, and the concentration is
determined using a comprehensive spectral fitting routine.

Description
CT5100 CGA installationFigure 3-2:
The CT5100 CGA contains an optical system with multiple lasers and a series of optical
components that provide an optical path, a heated multi-pass analysis cell, sample and
outlet ports that can be connected to a gas handling system, and control and analysis
electronics. The number of lasers installed depends upon customer requirements. The
complete system operates from either 100 or 240 Vac 50/60 Hz supply. You must specify
whether you want 100 or 240 Vac on your order.
Gas concentrations are measured using mid-infrared optical absorption spectroscopy. The
light sources are QCLs, which are operated to produce wavelength sweeps that cover the
absorption lines of the gases. The light from each laser is routed through an optical path to
the analysis cell, which provides measurement of low concentrations of the subject gases.
The sample gas is conditioned and drawn through the analysis cell by an external sample
handling system. The light exits the multi-pass analysis cell and is directed to a receiver in
the CT5100 CGA. The variation in the intensity of light in the vicinity of the absorption lines
is measured, and the concentration is determined using a comprehensive spectral fitting
routine.
There is no sample conditioning provided within the CT5100 CGA; the sampled gas must
be brought within the parameters shown in Table 4-3 before entering the CT5100 CGA.
Detailed characteristics of the CT5100 CGA are also given in Section 4.2.
