Mass Spectra (MS, MS Tracking)

If you have a Thermo Finnigan Mass Spectrometer installed, you can acquire mass spectra using Chromeleon. For more information about how to install the spectrometer and acquire data, refer to Using Mass Spectrometers.

In HPLC MS, mass spectra especially serve for peak identification. Using mass spectra for identifying substances is via the MS Tracking tab page. For more information, refer to Integrating Chromatograms and Identifying Peaks  Identifying Peaks via Their Mass Spectra.

As MS chromatograms normally show increased noise, you have to process Mass Spectra before you can use them. On the MS tab page, define the number of single peak spectra to be averaged. Also, define how many background spectra shall be aggregated into a total background spectrum that is then subtracted from the averaged peak spectrum.
