New Mass chromatogram

It is very useful to extract a MS spectrum by following the menu 'Mass Tools/New Chromatogram' or by clicking on the corresponding icon of the toolbar:

You can extract the MS chromatogram graphically or manually. To extract the MS graphically, just select the option and click on the MS (or click and drag if you want to select a range).

You can also select the range (or ranges, by clicking on the blue plus button) of the new chromatogram manually (and by using a molecular formula, so that the m/z value is calculated automatically to extract the corresponding new mass chromatogram):

This also can be done from the MS Browser ('New Chromatogram/Mass'):

You could also create a new chromatogram from a MS/MS function. In that case, if the provider supports it (such as Xcalibur from Thermoscientific), a scan filter dropdown will be displayed; showing the different precursors and collision energies. After having selected the desired filter, you will obtain the applicable chromatogram:

If you are interested in a Base Peak Chromatogram (BPC) for a selected mass range, just select the 'Base Peak' radio button and choose the desired range.
