Electron Multipliers & Replacement Horn
By Agilent Technologies
The lifetime of an EM is directly related to the current that flows through it and the extent of contamination or condensation that it experiences. To maximize electron multiplier life:
- Maintain the best possible vacuum, especially in the analyzer manifold.
- Use extreme caution and be conservative with venting, pumpdown, and all vacuum system procedures to keep pump fluid background to a minimum.
- After venting, allow four hours for pump-down and thermal equilibration before scanning.
- Actively look for background contamination and leaks and repair them immediately.
- Don t tune excessively. PFTBA can result in higher background over an extended period of time.
