Library Search
The Library Search option is only available by right clicking on a spectra chart. The Library
Search Spectra Graph shows the results of a library search and therefore is not used to initiate a
library search.
The library to be searched and the RI window size are set in the
Deconvolution Parameters tab
in Target Library Editor. Refer to the section of this chapter that describes the deconvolution settings
tab for instructions on how to select a library and how to set up the value for the windows.
Selecting the
Library Search… option opens the following dialog box.

Calculated Retention Index - This section allows the system to calculate the retention
index window in one of three ways. The retention index calibration data are a result of the
retention calibration setup in the Gas Chromatograph window of the Chromion software.
•
Retention index from file
uses the calibration information that is stored in the data
file.
• Retention index from file uses the calibration information that is stored in the data
file.
•
Manual calibration from method uses the retention index calibrations manually
added in Gas Chromatograph. Refer to the Gas Chromatograph section of this chapter
for instructions on setting up manual retention index calibrations.
•
Auto calibration from method
uses the retention index calibrations appearing in Gas
Chromatograph.
Retention index is the value appearing in the deconvolution window for the unknown
compound.

Range This section allows manual entry of values for any of the fields.
•
RI-/RI+ If wider windows are needed the values can be changed on this screen
without changing the default settings in the method.
•
Window The number of the Window is the plus and minus (+/-) of a value of the
retention index of the compound in which identification can be made of a compound.
The number is set the Window in Deconvolution Parameters of Target Library Editor for
the unknown library used when searching compounds. If the retention index is 475 then
