To print the spectrum and functional group bands, turn on IR Spectral
Interpretation Results Spectra. To print the contents of the table, turn on IR
Spectral Interpretation Table.
You can use the Printer Setup button to set parameters that affect how the
information will be printed; for example, the printer or paper orientation to use.
When you are finished, choose OK.
5. When you are finished viewing the results, choose Close to close the
Spectral Interpretation window.
Performing a
QC comparison
Note
Use QC Compare in the Analyze menu to verify the composition of a sample. The
command compares the spectrum of the sample with spectra in the specified QC
libraries and reports how well the spectrum matches the library spectra.
The spectra in a QC library are not independent (as in a 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 library is not a list of the best individual matches
in the library but instead a display of the single best match from each type.
If you want to identify an unknown spectrum, use Search in the Analyze menu.
See “Searching a spectral library” for details. ▲
You can include the entire sample spectrum in the comparison or just certain
spectral regions. The compared regions are determined by three things:
• The regions you have specified for the library using the Search Regions tab in
the Library Setup dialog box.
• Which regions were not blanked when you created the library.
• The region of the spectrum you have displayed or selected in the spectral window.
Only those portions of the spectrum which are within the selected region (or
displayed region if no region is selected) and within the regions of the library that
were not blanked and within any of the regions you specified for the library using
the Search Regions tab will be included in the comparison.
Perform a QC comparison
1. Use Library Setup in the Analyze menu to set up the QC comparison.
2. Select the spectrum whose composition you want to verify.
3. If desired, specify a spectral region to compare by selecting it with the
region tool or by displaying it in the spectral window.
The compared regions are determined by three things:
• Which regions you have specified for the library using the Search
Regions tab in the Library Setup dialog box.
