SYSTEMS AND METHODS FOR ARBITRARY QUADRUPOLE TRANSMISSION WINDOWING

摘要

Systems and methods are provided for shaping an effective transmission window used to select precursor ions for a precursor mass range of a sequential windowed acquisition experiment. For at least one precursor mass range, an ion transfer function is selected that is a function of mass using a processor. A quadrupole mass filter that transmits ions from a sample is instructed to produce two or more transmission windows over time using the processor. The two or more transmission windows are produced to cumulatively create an effective transmission window for the at least one precursor mass range with a shape described by the ion transfer function.
