Abstract
Systems and methods are provided for providing a DMS precursor ion survey scan. An ion source configured to receive a sample is instructed to ionize the sample using a processor. A DMS device configured to receive ions from the ion source is instructed to separate precursor ions received from the ion source and transmit precursor ions using two or more CoVs using the processor. A mass analyzer configured to receive transmitted precursor ions from the DMS device is instructed to measure the m/z intensities of the transmitted precursor ions across an m/z range at each CoV of the two or more CoVs using the processor. The measured m/z intensities of the transmitted precursor ions received from the mass analyzer are stored as a function of m/z value and CoV using the processor. This produces a stored two-dimensional mapping of m/z intensities of the precursor ions of the sample.
