3.3 Software Operation
The mass spectromter is designed to be operated from a computer
configured with Chromeleon software. Chromeleon software provides
complete instrument control, data acquisition, and data management.
The data system serves as the user interface to the mass spectrometer,
autosampler, LC pump, and syringe pump. Refer to the Chromeleon Help for
more information about the ISQ EC and ISQ EM Single Quadrupole Mass
Spectrometer data processing and instrument control. Each sequence of
loading a mass analyzer with ions followed by mass analysis of the ions is
called a scan. The mass spectrometer utilizes both a full scan type and/or
selected ion monitoring (SIM) scan type to create, fragment, and detect
ions. The ability to vary not only the ionization and ion polarity modes, but
the scan mode and scan type, provides greater flexibility in the
instrumentation for solving complex analytical problems.
The method editor in Chromeleon allows the user to set up scans in a
variety of ways, combining both full scans and SIM scans. The user can also
call for scans of either or both polarities. Simplified ion source controls and
a simplified method editor make setting up an instrument method easier
than ever, while the ability to switch to manual controls means that users
who wish to control each device independently do not lose that freedom.
For more information on the method editor, please see the help file in the
Chromeleon data system. Users can set up full scans to get a picture of the
entire mass spectrum as well as set up SIM scans to monitor for the
presence of specific ions. The ability to apply source collision induced
dissociation (sCID) gives the user the capability to reduce the presence of
adducts, or to create confirmation ions via fragmentation in the ion optics of
the system.
