Quadrupole mass spectrometer mass resolution and sensitivity is enhanced

摘要

Mass spectrometer novel method and apparatus can be introduced to determine the spatiotemporal pattern image of the exit of the ion (s) of the multipole device. In particular, the detectors are arranged, as a function of the spatial displacement of the beam cross section of the mass filter, the structure and method of the present invention measures the ion current and quadrupole time. In combination with the spatial structure when regeneratable that the linearity of the ion current quadrupole is detected, the contribution signal from the ion species separate complex mixtures in both the mass resolution and sensitivity is essential I allow the deconvolution.
