Abstract
The apparatus and method of the present invention multiplexes or gates particle beams to provide continuous data collection useful in time-of-flight mass spectrometry. The multiple particle beams are gated or combined to achieve an overall 100% duty cycle. This allows continuous data collection, thereby realizing the full advantages of abundance sensitivity and mass resolution in time-of-flight mass spectrometry.
