Before You Collect Spectra
Warning
The
Spectrometer Safety Guide
that came with your system contains
important safety information. This guide is available in several
languages. Contact your local Thermo Electron office for
information about the languages that are available. Before you use
the system, read the entire guide. To prevent personal injury and
damage to equipment, follow the safety precautions contained in the
guide whenever you use the system.

It’s easy to collect spectra with your spectrometer. By leaving the
system turned on at all times—with the needed components already
installed—you can keep it ready to use with a minimum of
preparation. Keeping the system on also improves its stability and
gives you more consistent results.
All the things you need to check before collecting spectra are listed
below; each of these items is discussed in a section of this chapter. By
the time you have run through these items once or twice in the course
of your work, you will know how to check the system and start
collecting spectra quickly.
•
Check the purge or desiccant.
•
Make sure the system components are powered on.
•
Cool the detector (if you are using an MCT, InSb or other
detector that requires cooling with liquid nitrogen).
•
Start OMNIC and select an experiment.
