Supporters of EVISA includes:
pulse count signal
The most sensitive ion detection method, in which each ion striking the detector creates an individual pulse. The count rate is limited by the recovery time (dead time) of the detector between pulses but is usually in the range from 1 to 106 counts per second for electron multipliers.
