Abstract
There is disclosed an apparatus for cytofluorimetric analyses including an optical system, based on at least one multi-channel photomultiplier allowing to condition the signals exclusively in the digital domain by means of a conditioning chain formed by routine software, the specific optimal operation parameters of which are obtained by means of methods which are also an object of the present invention, thus obtaining an efficiency which is so high that it allows more reliable and detailed analyses than in the past.
