WebThe "order" of a multipole guide, N, is obtained by dividing the number of poles by two: Four rods (Quadrupole), N=2; Six rods (Hexapole), N=3; ... they are more typically operated in higher pressure regions of mass spectrometers, with pressures ranging form ~1 Torr down to ~1 mTorr. As such, the ions are regularly colliding with neutrals as ... WebA mass spectrometer can measure the mass of a molecule only after it converts the molecule to a gas-phase ion. To do so, it imparts an electrical charge to molecules and converts the resultant flux of electrically charged ions into a proportional electrical current that a data system then reads. The data system converts the current to digital ...
