display called a spectrum then appears on the computer’s screen. The
spectrum is a graphic representation of the sample in terms of light
absorbed (or transmitted) by the sample at various frequencies (wave
numbers) along the spectrum. The size and position of the peaks in the
spectrum are used to identify or quantify the composition of the sample.
Figure 7–6 shows the infrared beam path and data processing steps.
The major system components provide the basic system functionality for
the instrument.
The spectrometer compartment provides the electrical and optical
functions. The major components it includes are the interferometer,
source, and laser. Where possible, the optical components are pinned-in-
place for easy service and maintenance.

The FTIR analyzer uses Thermo Fishser Scientific’s EverGlo source. The
source unit can be replaced as needed. It is pre-aligned and needs no
adjustment when it is installed.
