When the SelexION or SelexION
technology is installed on the mass spectrometer, users might need to

acquire spectral data without using the SelexION or SelexION
technology. Instead of removing the technology
®
from the system, users can use the DMS Off operation mode to acquire data. The Analyst software provides a
DMS Off operation mode, which allows the user to work in an environment similar to when the technology is not
installed on the mass spectrometer. However, in the DMS Off mode, signal intensities will be significantly decreased
as compared to the signal intensities of data acquired with the technology physically removed from the mass
spectrometer.
To work in the DMS Off operation mode, select the DMS Off check box available on the MS tab in the
Acquisition method window or on the MS tab in the Tune Method Editor window.
