PerkinElmer’s NexION® 5000 multi-quadruple ICP-MS instrument has four quadrupoles. The first, Quadrupole Ion Deflector (Q0), directs ions to the entrance of the first mass filter. The second, Transmission Analyser Quadrupole 1 (Q1, full-sized for <0.7 amu mass resolution), acts as a mass filter or as an ion guide to direct ions to the Quadrupole Universal Cell. The third, Quadrupole Universal Cell (Q2), using dynamic bandpass tuning, prevents side reactions with residual gases in the cell. The fourth, Transmission Analyser Quadrupole 2 (Q3, full-sized for <0.7 amu mass resolution), acts as a mass filter or as an ion guide to direct ions to the detector.

The Extended Dynamic Range (EDR) feature increases linear dynamic range to 1012, allowing both high and low concentration analytes to be handled in a single analytical run, resulting in fewer re-runs. The instrument also has a number of improvements to reduce maintenance for greater uptime. A Triple Cone Interface with patent-pending OmniRing™ combined with a quadrupole ion deflector allow no maintenance beyond the cones, for continual operation and improved stability. The 34-MHz free-running RF generator is air cooled (no water or gas cooling), so is maintenance-free, eliminating need to replace plasma load coils.
