摘要
A time-of-flight mass spectrometer comprises an ion source, a segmented linear ion storage device having at least one segment defining an extraction region, voltage supply means for supplying trapping voltage and extraction voltage to the ion storage device and a time-of-flight mass analyser for performing mass analysis of ions ejected from the extraction region. The extraction region includes first and second electrode means. The trapping voltage includes first RF trapping voltage supplied to the first electrode means to form a one-dimensional ion cloud and a second RF trapping voltage supplied to the second electrode means to transform the one-dimensional ion cloud to a two-dimensional ion cloud.
