Transmission quadrupole mass spectrometer
From Mass Spec Terms
DRAFT DEFINITION |
Transmission quadrupole mass spectrometer |
---|
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. |
Considered between 2004 and 2006 but not included in the 2006 PAC submission |
