• Atmospheric pressure photoionization (APPI)
• Nanospray ionization (NSI)
The ion optics focus and accelerate the resulting gas-phase sample ions into the
where they are isolated and ejected according to their mass-to-charge ratios. As the mass
analyzer ejects the sample ions, they are detected by a detection system that includes one or
two electron multipliers and that produces a signal proportional to the number of ions
detected. The system electronics receive and amplify the ion current signal from the ion
detection systems. The signal then passes on to the data system for further processing, storage,
and display. The data system provides the primary mass spectrometer user interface.
