Understanding Peak Finding 111

Figure 49. Slope Values
Although the region before 23 sec is baseline, the slope ranges
between ±15 /sec. Setting the slope threshold much below 15/sec
causes the analysis to detect these noise bumps as peaks. The
bumps will not be identified as peaks because they do not meet the
Minimum Height and/or Minimum Width thresholds, but the analysis
runs much slower as it carefully explores each bump. Also, the
analysis will have difficulty finding baseline regions of qualifying
width.
