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 is located a the bottom left hand side of the TIC window. It
provides the analyst with the ability to average spectra over a "range" of scans
across a given peak. This is helpful when analytes are low in concentration. It can
also be used to select a section of a peak if there is co-elution. The ability to
establish a range and average its spectra allows for better matches with the NIST
database.
Figure 9-14 displays a TIC/RIC window with the range function in use.
NOTE: All ranges are indicated in the Scan/Spectrum window by the designation:
R1 [Range Start Scan, Range End Scan].
