摘要： A time-of-flight mass spectrometer (1) comprises an ion source a segmented linear ion device (10) 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 (10).

摘要： A multi-reflecting TOF mass analyser has two parallel, gridless ion mirrors each having an elongated structure in a drift direction (Z). These ion mirrors provide a folded ion path formed by multiple reflections of ions in a flight direction (X), orthogonal to the drift direction (Z). The analyser also has a further gridless ion mirror for reflecting ions in the drift direction (Z). In operation ions are spatially separated according to mass-to-charge ratio due to their different flight times along the folded ion path and ions having substantially the same mass-to-charge ratio are subjected to energy focusing with respect to the flight and drift directions.
