*   Using the Mass Differences Page
Use the Mass Differences page in the Database Manager window to select any peak and view the mass differences to the right and left (possible precursor-product ions). You can move the m/z scale using the track bar at the top of the page. When molecular mass information is available, the zero value of the m/z scale automatically starts at the molecular mass—that is, a standard neutral loss spectrum is displayed. In this case, a blue selection bar in the track bar marks the shift of the m/z scale with respect to molecular mass. You can enlarge the graphic to see the number for less prominent peaks when there are a large number of peaks close to each other.
