  • Multiplex data acquisition modes for ion mobility-mass spectrometry
    Patent number: 7388197
    Abstract: A method and apparatus for multiplexed data acquisition for gas-phase ion mobility coupled with mass spectrometry is described. Ion packets are injected into an ion mobility drift chamber at a rate faster than the ion mobility separation arrival time distribution. The convoluted arrival time distributions thus generated are deconvoluted by a mass spectrometer and post-processing algorithms.
