ABSTRACT
This chapter describes some apparatuses. Their choice is grounded on their usefulness notably in bioanalytical chemistry. Given this choice, all the components which possibly constitute mass spectrometers cannot be described here. This is the reason why some compliments are given. An important part is consecrated to the inductively coupled plasma mass spectrometry (ICPMS). For this kind of apparatus, are reviewed the plasma, the inlet and the ion source the ionization and atomization are carried out in a plasma torch, the interface torch/SM, the quadrupole analyzer and its principle of functioning and the detectors found in this kind of apparatus. ICPMS can carry out analysis of numerous elements. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF/MS) and electrospray ionization mass spectrometry (ESI-MS) is also studied in some length. This is also the case with some components of mass spectrophotometers that have not yet been cited.
