4. Ion detection and signal conversion

This is the intermediate step between discriminating ions according to their m/z ratio and displaying the mass spectrum of the species analyzed. Detectors are often referred to as the "eyes" of the analyzer. There are currently two main detection methods :

  • one takes into account the interaction between the ion and a detector surface, the properties of which enable the emission of a secondary electron or photon from the impact of the incident ion...
