The four peak find setpoints that can be changed are:

Min Peak Height The Min Peak Height setpoint determines whether a peak is kept.

For each peak, the difference between the start point value and the

center point value (local baseline) must be greater than the Min

Peak Height value.

Min Peak Width The Min Peak Width setpoint determines the minimum amount of

time that must elapse before a peak is recognized.

Slope Threshold The Slope Threshold setpoint determined the difference in the

slope that must occur in order for a peak to begin. The inverse of

this value is used to determine the peak end.

Baseline Plateau The Baseline Plateau setpoint is a parameter that assists in finding

peaks. The signal is recognized to be at baseline whenever the

slope of the data is less than the Slope Threshold setpoint (either

positive or negative) for longer than the time set for the Baseline

Plateau. This setting rejects brief, low slope areas such as between

non-baseline-resolved peaks.
