Working with libraries
Click the Library Names tab to display the contents of libraries and perform
various operations on libraries.
There are three types of libraries:
Search libraries are collections of reference spectra that you can use to identify
unknown spectra.
QC (QC Compare) libraries let you verify the quantitative composition of materials.
These libraries are useful for quality control operations in which you know what a
sample should contain and just need to verify and document the composition.
Note
The spectra in a QC library are not independent (as in a traditional search library)
but instead are grouped into compound types. Because of this, the result of
comparing a sample spectrum with the spectra in a QC Compare library is not a
list of the best individual matches in the library but instead a list of the best match
from each type. ▲
Scrapbook libraries are a convenient place to store and organize your spectra.
You can add any spectrum to a scrapbook library; the resolution and other
parameters do not matter. After adding spectra to the library, you can find them by
search for text stored with the spectra. You cannot perform a spectral data search
of a scrapbook library.
These types of libraries are contained in three “books” at the left side of the
Library Names tab. To view the libraries contained in a book, click it. The book
opens and the libraries contained in it appear as books. (If there are no libraries in
a book, it does not open.)
