ES5 Bi-Polar Electrospray
-5kV to +5kV Module for Mass Spectrometers

Applications:

  • Electrospray
  • APCI
  • Deflector plates

This power supply provides up to +5kV for electrospray & APCI applications. Output polarity can be remotely changed by control pin voltage. As the unit does not use high voltage relays the polarity can be repeatedly changed at high speed without reducing the life of the unit. The power supply is to operate under current control in electrospray & APCI applications in mass spectrometers. Please consult the factory for special variants of this supply including higher speed versions.

Electrical Specification

INPUT VOLTAGE:

+24V d.c. ±0.5V at 0.7A, current control option needs -15V d.c.±0.5V at 0.02A.

OUTPUT VOLTAGE:
