Abstract
Systems and methods prevent potentially convolved precursor ion peaks from being excluded in subsequent cycles of an IDA experiment so that additional product ion data is collected. A sample is ionized producing an ion beam. A plurality of cycles of an IDA experiment are performed on the ion beam. During each cycle of the IDA experiment and for each precursor ion peak on a filtered peak list produced in the filtering step of each cycle, several steps are performed. The precursor ion peak is identified in the precursor ion spectrum produced in the MS survey scan step of the cycle. It is determined if the precursor ion peak in the precursor ion spectrum includes a feature of convolution. If the precursor ion peak includes a feature of convolution, the precursor ion peak is prevented from being excluded in a filtering step of one or more subsequent cycles.
