About Spectral Methods
In Chapter 8. Performing Operations on Chromatograms you will learn about the
chromatographic operations in IRIS, which allow you to obtain important information about
your chromatograms. These operations include Peak Purity (which checks the homogeneity
of each peak in the chromatogram), Peak Library Search (which identifies each peak in the
chromatogram by comparing its spectrum to a spectral library), and Spectral Standard
Confirmation (which confirms the identity of each peak in the chromatogram by comparing
its spectrum to the spectrum from the same named peak in a reference chromatogram).
However, before you begin performing these operations it is important that you learn about
how these operations are calculated. In IRIS all of the parameter values used to calculate
the results of an operation are stored in spectral method files.
There are three types of spectral methods in IRIS: Default Method, Chromatogram’s
Spectral Method, and a Process Spectral Method. Following is s description of each
method and how it is used by IRIS.
