Popis:	Detector dead time in electron multiplier ion counting applications has been reduced. A first‐in first‐out buffer allows a traditional ion counting system to accept pulses 10 ns apart. Lower dead time (10 ns) results from elimination of electrical ringing that trails electron multiplier output pulses. The improved system has been tested on 34S/32S isotope ratio measurements.
