How does the ion detector work?

In all mass spectrometers other than FT-ICR instruments, the ions are detected after mass analysis by converting the detector-surface collision energy of the ions into emitted ions, electrons, or photons that are then sensed with various light or charge detectors. In FT-ICR mass spectrometers the oscillating signal induced by orbiting ions in the detect plates is used for ion detection.

What are the role of computers in mass spectrometry?

Because of the large amounts of information that can be generated and the large number of parameters to be changed in a short period of time, computers are essential for mass spectrometer control and for spectrum acquisition, storage and presentation. Computer-based data systems also typically include software for quantitation, spectral interpretation, and compound identification through use of on-line spectral libraries.
