Peak Detection

Adaptive-slope algorithm that applies user-specified parameters to accommodate drifting baselines, negative and asymmetrical peaks, or absolute threshold level that collects all peaks above specified mV value

Peak parameters: peak height or level, in mV and peak width at half-height, in minutes

Minimum peak height for fractionation: 0.1 mV full scale

Detector-collector delay: 0.01 minute increments
