1-6 Waters Xevo G2 QTof Overview
Software and data system
Waters informatics software controls the mass spectrometer. The software
acquires, analyzes, manages, and distributes data from mass spectrometry,
ultraviolet (UV), evaporative light scattering, and other sources.
Waters informatics software enables these major operations:
• Configuring the instrument.
• Creating LC and MS methods that define operating parameters for a
run.
• Tuning and mass calibrating the mass spectrometer.
• Running samples.
• Monitoring sample runs.
• Acquiring data.
• Processing data.
• Reviewing data.
• Printing data.
See the online Help for more information
Instrument Console
The Instrument Console is an area within the Waters informatics software in
which you configure settings, monitor performance, run diagnostic tests, and
maintain the mass spectrometer. The instrument console functions
independently of the data and does not recognize or control the data software.
See the online Help for details.
LockSpray source and ionization modes
The LockSpray source uses lock-mass correction to acquire exact mass data.
The analyte is introduced into the source through a probe. A reference flow,
containing a compound of known mass, flows through a separate ESI probe.
An oscillating baffle allows the sprays to be analyzed as two separate data
functions. The lock-mass correction calculated from the reference data is then
applied to the analyte data set.
You can use the LockSpray source with the ESI, APCI, and ESCi ionization
modes. See Chapter 3 “Configuring the LockSpray Source” .
