For information on controlling your LC devices from the Xcalibur data system, refer to the
online Help available from the Xcalibur Instrument Setup window. Front-panel (keypad)
operation of the LC devices and maintenance procedures for the LC devices are described in
the documentation provided with the LC.

You use the reference inlet system to introduce calibrant solution into the MS detector to
perform a Full System Autotune or a Mass Scale Calibration, which is a subset procedure of
the Full System Autotune procedure.
During an automated Full System Autotune procedure, the Surveyor MSQ Plus MS detector
and instrument control software perform these steps:
• The MS detector infuses the calibrant solution and the software electronically adjusts the
resolution of the peaks at low, mid, and high mass. The resolution of the peaks is adjusted
to unity Dalton at their baselines.
• Performs a Mass Scale Calibration. During a Mass Scale Calibration, the software
performs these steps:
−
Compares the empirically determined masses of the factory-supplied calibrant
solution to a reference file of the same compound that contains the correct mass for
each peak.
−
Adjusts the empirically determined masses in the acquired data file to match those in
the reference file.
