Use of peak detection circuits with single-particle detectors and multichannel analyzers.
The need, method and calibration, and results of using a peak detector interface with a Royco 220 light-scattering single-particle detector and a multichannel analyzer are presented. Two methods of peak detection are discussed. A third design is presented that is capable of handling 50 to 7500 signals/sec without introducing appreciable dead time into the system.
