Quadrupole — A quadrupole or quadrapole is one of a sequence of configurations of for example electric charge or current, or gravitational mass that can exist in ideal form, but it is usually just part of a multipole expansion of a more complex structure… … Wikipedia
Quadrupole ion trap — Scheme of a Quadrupole ion trap of classical setup with a particle of positive charge (dark red), surrounded by a cloud of similarly charged particles (light red). The electric field E (blue) is generated by a quadrupole of endcaps (a, positive)… … Wikipedia
Quadrupole magnet — Quadrupole magnets consist of groups of four magnets laid out so that in the multipole expansion of the field the dipole terms cancel and where the lowest significant terms in the field equations are quadrupole. Quadrupole magnets are useful as… … Wikipedia
Quadrupole mass analyzer — The quadrupole mass analyzer is one type of mass analyzer used in mass spectrometry. As the name implies, it consists of 4 circular rods, set perfectly parallel to each other.cite book|last=de Hoffmann|first=Edmond|coauthors=Vincent… … Wikipedia
Electric field gradient — Mathematically, the electric field gradient (EFG) is the hessian matrix (the matrix of the second derivatives) of the electrical potential V: :V {ij} = frac{partial^2 V}{partial x i partial x j}It is an important structural property of a… … Wikipedia
quadrupole — noun a) a distribution of either electric charge or magnetization equivalent to two dipoles that point in opposite directions b) a magnet with two north poles and two south poles, used to focus a beam of particles … Wiktionary
