Inlet Ionization
In mass spectrometry, matrix-assisted ionization (also inlet ionization) is a low fragmentation (soft) ionization technique which involves the transfer of particles of the analyte and Matrix (mass spectrometry), matrix sample from atmospheric pressure (AP) to the heated inlet tube connecting the AP region to the vacuum of the mass analyzer. Initial ionization occurs as the pressure drops within the inlet tube. Inlet ionization is similar to electrospray ionization in that a reverse phase solvent system is used and the ions produced are highly charged, however a voltage or a laser is not always needed. It is a highly sensitive process for small and large molecules like peptides, proteins and lipids that can be coupled to a Liquid chromatography–mass spectrometry, liquid chromatograph. Inlet ionization techniques can be used with an Orbitrap mass analyzer, Orbitrap Fourier transform ion cyclotron resonance, fourier transform mass spectrometer, Quadrupole ion trap, linear trap qua ...
