Abstract
A method is provided for mass spectrometry. The method includes generating precursor ions from a sample; transmitting the precursor ions into a collision cell; generating product ions in the collision cell; detecting the precursor and product ions; applying modulation to one or more of the precursor ion intensity and the product ion intensity; and identifying precursor ion and product ion relationships by analyzing intensity profiles defined by the modulation.
