Abstract
An analyzer for electrophoretic samples has a sample stage movable linearly with respect to a source and a detector of analysis energy. During a first scan of the sample, a voltage is produced representing either the minimum detected fluorescence or the minimum detected optical density. During a second scan, the voltage is combined with the output of the detector to automatically correct the output to a reference.
