| ES008RCP150 BI-POLAR ELECTROSPRAY 8 kV MODULES
Applications:
Electrospray
APCI
Deflector plates
This power supply provides up to ±8kV for electrospray & APCI applications. Output polarity can be remotely changed by control pin voltages. 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 can be operated under current control in electrospray & APCI applications in mass spectrometers. Please consult the factory for special variants of this supply including higher speed versions, for volume applications.
