    Sainmhíniú type of mass analyzer used in mass spectrometry which consists of 4 circular rods, set highly parallel to each other Tagairt "Wikipedia > Quadrupole mass analyzer. http://en.wikipedia.org/wiki/Quadrupole_mass_analyzer [12.11.2010]"
    Nóta The quadrupole is the component of the instrument responsible for filtering sample ions, based on their mass-to-charge ratio (m/z). Ions are separated in a quadrupole based on the stability of their trajectories in the oscillating electric fields that are applied to the rods.These mass spectrometers excel at applications where particular ions of interest are being studied because they can stay tuned on a single ion for extended periods of time. One place where this is useful is in liquid chromatography-mass spectrometry or gas chromatography-mass spectrometry where they serve as exceptionally high specificity detectors. Quadrupole instruments are often reasonably priced and make good multi-purpose instruments.

    Sainmhíniú spectromètre de masse dans lequel les ions sont injectés selon l'axe d'une lentille quadripolaire, formée par un système de quatre électrodes, généralement en forme de barres rondes, lentille à laquelle on applique une tension radiofréquence et une tension continue, maintenues dans un rapport donné Tagairt X 10-502:1980

    Sainmhíniú tandem mass spectrometer consisting of two quadrupole mass spectrometers in series, with a (non mass-resolving) radio frequency (RF) only quadrupole between them to act as a collision cell for collision-induced dissociation Tagairt "Wikipedia > Triple quadrupole mass spectrometer. http://en.wikipedia.org/wiki/Triple_quadrupole_mass_spectrometer [12.11.2010]"
    Nóta The first (Q1) and third (Q3) quadrupoles serve as mass filters, whereas the middle (q2) quadrupole serves as a collision cell. This collision cell is an RF only quadrupole (non-mass filtering) using an inert gas such as Ar, He, or N2 gas to provide collision-induced dissociation of a selected precursor ion that is selected in Q1. Subsequent fragments are passed through to Q3 where they may be filtered or scanned.
