Abstract
In a three-dimensional Paul RF ion trap the ring electrode and end cap electrodes are formed from pairs of pole rods. This multipole rod system is then operated as a linear ion trap with a constant field distribution along the multipole rod system. While the system is operating as a linear ion trap, analyte ions are introduced and stored within the linear ion trap. After the ions have been stored, a single-phase RF voltage is supplied to all rods of a middle segment thus forming a three-dimensional ion trap, thereby collecting the ions in a spherical cloud within this middle segment. The collected analyte ions can then be reacted in the three-dimensional ion trap and the product ions resulting from the reactions can be ejected for mass analysis.
