Electron Multiplier, API 2000 / 3200 and 3200 Q-TRAP (ETP Multiplier)

Exceptionally sensitive discrete dynode electron multiplier with long operating life and excellent air stability.

ETP 14610 Detector for API 2000 LC-MS Instruments

The 14610 is a direct replacement multiplier for the API 2000 instruments. Sockets on the 14610 mounting base connect directly with the electrical pins of the API instrument.
Connections are:

 -HV
 +HV
 Deflector
 Output Signal

ETP electron multipliers incorporate air-stable "ACTIVE FILM" materials in a discrete-dynode multiplier design.
