Abstract
A time-of-flight mass spectrometer () comprises an ion source a segmented linear ion device () for receiving sample ions supplied by the ion source and a time-of-flight mass analyzer for analyzing ions ejected from the segmented device. A trapping voltage is applied to the segmented device to trap ions initially into a group of two or more adjacent segments and subsequently to trap them in a region of the segmented device shorter than the group of segments. The trapping voltage may also be effective to provide a uniform trapping field along the length of the device ().
