This allows for the simultaneous detection of a range of energies in the photoelectron spectra and thereby improves the data quality for a given period of data accumulation, compared to using a conventional electron multiplier
behind an exit slit.
The transmission of the ions, continuously produced in the ion source of a quadrapole mass spectrometer, through the quadrapole mass filter to the electron multiplier
is relatively inefficient (<5%, see Figure 5a).

For Inductively Coupled Plasma Mass Spectrometer (Icp-Ms) Etp Multiplier,Model No.
The electron multiplier
voltage was set at 600 V above the El-tune voltage.
Positive ion detection may be achieved using either a Faraday plate detector or an analogue Channel Electron Multiplier
(CEM) if better detection limits are required.
