A quadrupole mass spectrometer has four rod electrodes arranged in parallel that form the quadrupole field. Their points of intersection with a plane lying perpendicular to the cylinder axis form a square (thus the name quadrupole).
A static electrical field accelerates the ions before they fly through the quadrupole field. The quadrupole field between the rods allows only one particle of a given mass to pass through at a time, thus effecting the selection. Quadrupole mass spectrometers are available in high-resolution versions as well as in a more affordable version for use as a residual gas analyzer. Thanks to this bandwidth, these kinds of mass spectrometers are employed in numerous fields, ranging from pharmacology to environmental analysis.
