Calibration pane

The Tune application includes a Calibration pane that provides the software controls to check and calibrate your MS. A simplified user interface displays a quick view of the current system calibration state and its status.

NOTE For more information about the Calibration pane, see Calibration Pane.

Calibration modes

The following modes are used to check and calibrate your instrument:

• Check, Calibrate if required: This option completes a check of all system calibration items, calibrates any item that requires it, and then reports back the status. Changes to the system are made only when necessary.
• Calibrate: This option performs a full calibration of all items on your system. Changes are made to any and all items that require calibration. The system then reports back the status.

Automated control of calibration operations

To achieve the most effective results, the system check and calibration process is automated. You provide input on a few aspects of the operation, then the software begins the check and calibrate process, and automatically runs through the calibration steps to completion. The Tune application reports the results, which can be customized from the Tune Preferences dialog box. See Tune Preferences.

Calibration sets

The calibration is categorized by “sets”. These are the items that are calibrated by the system. For example, the System set includes many standard items, such as the ion optics, quadrupole, and ion trap.

Calibration order of operations

The Tune application automatically enforces dependencies between certain instrument calibrations, ensuring that each aspect of instrument performance is checked and/or calibrated only after any its dependencies have been checked and/or calibrated. If any particular item fails its check, then any items which depend on that failed calibration are skipped.

Spray stability and calibration solution purity checks

The stability and composition of the ion beam that is delivered to the MS directly influences the ability to run instrument checks and/or calibrations. Validating the ion beam stability and composition is always enforced prior to running any other system checks or calibrations. If the spray is unstable or the calibration solution is contaminated, the process stops and troubleshooting steps are provided in the Tune window.

Diagnostics pane

A Diagnostics pane provides item-specific instrument calibration parameters. As a standard user, you can access limited parameters to run specific, per-item, calibrations.

NOTE The Diagnostics pane is typically used by a Thermo Fisher Scientific service engineer during the installation or service.
