“…As observed in Ref. 7 for similar ion energies, the IPD gives good signals for molecules as large as 30 000 Da, confirming that the IPD/MCP ratio probably does not change much for larger ions, at least up to ca. 30 000 Da.…”

“…As already demonstrated 7 , the IPD can successfully be used with single event counting experiments and analog measurements. An appreciable advantage of the IPD is that the electron amplification process is achieved in the photomultiplier via a discrete dynode amplification chain.…”

An alternative detector for time-of-flight mass spectrometry, the ion-to-photon detector, detecting light produced when ions impact a surface coated with a fluorescent compound, was compared to a conventional microchannel plate detector. Single ion experiments showed that, for a given energy, the efficiency of the ion-to-photon detector relative to the microchannel plate detector decreases as the molecular mass of the impinging ion increases. This decrease becomes less pronounced for larger ions. Seen as a function of the ion velocity, a linear relationship was found. The conversions into photons and electrons were also compared. It was found that 22 keV ions up to 150 Da produced more photons than secondary electrons. For larger ions at this energy, the opposite was observed.

“…Conventional MS has relied on ionization-based detectors, namely those producing and multiplying secondary electrons associated with particle bombardment of a metal surface; such detectors are restricted to ions having a mass less than 10 6 Da. An ion-to-proton conversion detector (IPD) shows promise for detecting macro-ions (Dubois et al, 1997;Dubois et al, 1999). Photosensitive detectors, relying on laser-indued fluorescence (LIF) or elastic light scattering (ELS), show promise in this area.…”
