Abstract:
A mass spectrometry (MS) method which includes generating in a vicinity of the quadrupole ion trap hydrogen molecules, directing at least part of the hydrogen molecules into the quadrupole ion trap cell, applying AC and DC voltages to quadrupole ion trap cell electrodes to create a combined AC/DC trapping field, placing sample ions inside the quadrupole ion trap cell, cooling at least part of said ions using said hydrogen molecules as a buffer gas, changing the combined AC/DC trapping field to eject the ions from the quadrupole ion trap cell, and detecting the ejected ions.
