Library Editor
The Library Editor is used to look at and modify unknown libraries. After the libraries have been
refined they can be used on the instrument. The image below displays the Library Editor when first
opened.
The Chromion software comes with the AMDISNISTEPACW library. This library is an edited version
of the NIST AMDIS EPA library (retention index values have been added). This library consists of
data that are generated on quadrupole mass spectrometers. The unknown search algorithms in most
cases work well to match the data from the ion trap to NIST libraries. This library is not editable. If
modification to the data is needed for future searches a copy can be created and then edited.
Be sure to name the copy with a name that does not contain AMDIS . A file that contains the
word AMDIS either as part of the name or as the whole name will become protected.
CAUTION
The difference betw een Target Lists and libraries is primarily
the origin of the data came from. It is important to note that
some library data w ere generated on instruments that may give
slightly different spectra than the Torion T-9 instrument. This is
because different types of mass spectrometers w ork in different
w ays.
It is usually best to generate Target Lists on the instrument
being used for the actual w ork using standards of the analytes
of interest. Second best is to use compounds from libraries that
have been generated using another Torion T-9 GC-MS
instrument.
