Systems and methods for detecting and identifying the presence of an analyte in a sample using a high resolution mass spectrometry system. In an implementation the method includes ionizing an analyte to yield ions, passing the ions into the mass spectrometry system, fragmenting a portion of the ions passed into the mass spectrometry system such that there may be both fragment ions and non-fragmented ions passing through the system, identifying a first signal associated with the fragment ions, identifying a second signal associated with the non- fragmented ions, multiplying the first signal with the second signal to derive a third signal, and analyzing the third signal to identify a peak that is indicative of the presence of an analyte. |
