9.5.3 Utilizing the Range Tool
WARNING
Be careful not to leave out data/peaks that may be needed
for proper identification within the chromatogram.
The Range Tool provides the analyst with the ability to average spectra over
a "range" of scans across a given peak. This is helpful when analytes are in low
concentrations or to select a section of a peak when there is co-elution. The ability
to establish a range and average the spectra within that range will allow better
matches with the NIST database. The range tool is the triangle with the two red
vertical lines located at the bottom left hand of the TIC window.
Figure 9-14 displays a TIC/RIC window showing how it would look if ranging is
initiated.
NOTE: All ranges are indicated in the Scan/Spectrum window by the designation:
R1 [Range Start Scan, Range End Scan].
