http://www.massspecpro.com/technology/mass-analyzers/quadrupole-ion-trap-qit WebbIonized molecules and fragments are then accelerated through the instrument’s mass analyzer, which quite often is a quadrupole or ion trap. It is here that ions are separated based on their different mass-to-charge (m/z) ratios. GC-MS data acquisition can be performed in either full scan mode, to cover either a wide range of m/z ratios, or ...
