Peak Identification
Peak identification involves generation of a peak baseline using the
Slope Threshold and Baseline Plateau, detection of each peak
using Slope and Inflection Thresholds, and then discarding peaks
using the Minimum Height and Minimum Width thresholds. This
process only occurs between the Start Time and End Time peak find
properties. The Minimum Height threshold sets the minimum peak
baseline-to-peak apex value needed for a peak to be identified by
the analysis. The Minimum Width is the minimum left edge-to-right
edge value needed for a peak to be identified.
