A mass spectrometer data dependent method and apparatus is introduced to alter scanning parameters based upon data acquired during that scan. Such a method an apparatus may include the identification of ion species of interest meeting user specified criteria so that a determination can be made as to whether or not the present scan is to be continued, terminated, or alternatively paused while such a decision is being made. Such a method of operation saves overall cycle time and allows examination of, for example, marker ion ratios for additional peptides that might otherwise be missed.
