MOMENTUM ACCELERATION ORTHOGONAL TIME OF FLIGHT MASS SPECTROMETER

摘要

A method of orthogonal time of flight spectrometry is based upon applying a short, high voltage pulse to an electrode (315) to give ions (340, 350) within a pushout region (300) a constant momentum acceleration rather than a constant energy acceleration, thereby all ions (340, 350) in a beam (290) passed into the pushout region (300) are accelerated through a drift tube (325) and to a detector (330) at the same time.
