Resolving Power and Mass Resolution
of 0.05 amu at a mass of 500.0000 amu, the mass resolution is 10,000. For compari-son, the same 500 amu measured on a SQMS or quadrupole MS/MS system with typical ion widths of 0.6 amu has a mass resolution of approximately 833. It is evi-dent that the more narrow the ion width, the better the ability to distinguish similar masses.

www.ecs.umass.eduThe quadrupole is a mass filter which only allows ions having a limited range of m/z values reach the transducer. Ions that are not of the correct m/z collide with the rods or exit the path between the rods and are pumped out of the system. Quadrupole instruments easily resolve ions that differ in mass by one unit.
