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.

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.
