Patent

CA 2437187

A mass spectrometer is disclosed wherein a relatively energetic pulse of ions having a relatively narrow spread of mass to charge ratios are ejected from a quadrupole ion trap T2 and received in an ion trap TO upstream of a Time of Flight mass analyser. The ions are collisionally cooled within the ion trap TO and are pulsed out of the ion trap TO and into an extraction region 3 of the Time of Flight mass analyser without substantially exciting the ions. This enables improved operation with the Time of Flight mass analyser. According to another embodiment parent ions are fragmented and the resulting fragment ions are stored in two ion traps having different low mass cut-offs. The trapping system enables MS/MS experiments to be performed with a very high duty cycle.
