NOTE
It is not possible to delete the first master calibration.
Calibrations, which are embedded in an application, can never be deleted.
NOTE
Calibrations, which are already used for sample measurement in the application, can be never
deleted.
Optimize the Calibration
In order to optimize a calibration manually, the first calibration can be edited or copied: Lifecycle /
Edit or Copy.
Running the calibration wizard, several new calibrations are available, the calibration with the highest
Q-Value is activated.
A new empty calibration can be created: menu Calibration / New.
Save the Calibration for Application
The adjustment of the best calibration -mainly wavelength, pretreatment and PCs selection- is
suggested to be copied into the first calibration in order to keep these adjustments for further
changes. Unnecessary calibrations should be deleted before saving the project into the Database.
The best, activated and validated calibration should be stored for the application, for this the Lifecycle
/ Next should be used.
The calibration will get the Approved state using Lifecycle / Next.
NOTE
Only calibrations with Lifecycle state "Approved" are available for use in the routine applications for
the operator user group.
The Designer and Administrator user groups can use created or checked calibrations for test.
Validate the Calibration
In the calibration process released samples with known properties should be measured together with
the calibration samples. These samples should be placed in the V-Set of the calibration: internal
validation.
When a calibration is created and released for the application, the application should be also
validated: external validation. This is made with several new, known samples, which are not yet in
the calibration: operation qualification - OQ. These samples should be measured also with the
conventional laboratory method. In case the results of NIR and lab are the same (identification,
qualification) or they are within the allowed tolerances (quantitative determination), the calibration can
be used for the routine measurement till the next performance qualification - PQ.
