Collision induced reactions are also applied in ICP-MS with an ion trap for high mass resolution measurements. Two instrument configurations of the plasma source ion trap (PSIT) are shown in Figure 5.8 a and b, respectively. PSIT I utilizes a linear quadrupole for ion transport and mass selection (Figure 5.8 a) while the PSIT II applies direct injection of ions into the trap (without...

There are several types of ionization sources [MALDI, ESI, FAB (fast atom bombardment), PD (Cf-252 plasma desorption), El (electron ionization), Cl (chemical ionization) etc.], different types of mass analyzers [combinations of magnetic and electric sectors, quadrupolar filters (Q) and ion traps (IT), time-of-flight (TOF) and FT-ICR] and different detectors, each with its own advantages and drawbacks. We describe herein only the systems that presently have widespread use for the study of biomolecules ESI coupled to a quadrupole (or triple quadrupole, QqQ) mass analyzer or an ion trap, the MALDI source with the linear or reflectron TOF analyzer, and the FT-ICR system which can be equipped with both ESI and MALDI sources.
