You can also correct for baseline slope in your spectra. In Spectrum you can do this in two
ways: using an automatic baseline correction, or using an interactive baseline correction
(i-baseline) that enables you to define base points for the conversion (Figure 38).

NOTE: The Processing Your Data tutorial includes a description of ordinate-unit
conversion, automatic baseline correction, and peak detection and labeling.
Identification
Several processes in Spectrum can be used to help identify your sample.
Peak Table
The results of a peak table can be used to compare peaks with another sample – for
example, one published in a pharmacopoeia. The results of the process are displayed on the
Peak Table tab in the Viewing Area (Figure 39).


Select Peak Detection from the Setup menu to display the Setup Peak Detection tab
and define the thresholds and the algorithm used to identify the peaks.
NOTE: You can also add peak labels to the spectrum using the same thresholds using the
Label Peaks option on the View menu.
