A [[mass spectrometer]] that consists of four parallel rods whose centers form the corners of a square and whose opposing poles are connected. The voltage applied to the rods is a superposition of a static potential and a sinusoidal radio frequency potential. The motion of an ion in the x and y dimensions is described by the [[Matthieu equation]] whose solutions show that ions in a particular [[m/z]] range can be transmitted along the z axis. | A [[mass spectrometer]] that consists of four parallel rods whose centers form the corners of a square and whose opposing poles are connected.
