The calibration model wizard is used for creating and editing quantitative
calibrations. Calibration spectra and suitable parameters will be
adjusted here to get a calibration model for evaluation of samples in
routine analysis. One or more physical properties of a sample can be evaluated
according to numeric values (constituents/properties) which must be attached
as label to all calibration
spectra. This should be done before you start the calibration process,
although editing of the property values is also possible from within the
Creating a new calibration requires a set of calibration spectra. The
following preparative steps are mandatory:
Add / Edit labels
The properties to be calibrated containing e.g. concentration values
must be stored in a corresponding label before starting a new calibration.
For this purpose a Label
Editor dialog is available, which allows editing labels in
a spread sheet. If you need to make corrections the label editor is also
available from within the wizard.
The wizard will only accept the calibration spectra
as part of a project. Add the
calibration to a project or load a project which contains the spectra.
Select the project in the Project Explorer
and start the Calibration Model Wizard.
At least two spectra need to be added to the calibration
set in order to perform a successful calibration. The exception
is the univariate calibration
which can be performed with only one spectrum. In that case the option
Data Origin is Zero will
be automatically activated and an additional dummy spectrum with (0,0)
data values will be added to the calibration set and calibration project.
Depending on your license not all calibration
models may be available!
Your licensing model may not support the
full quantify package. In this case only the Univariate
Calibration will be available. Please contact your vendor for information
on how to purchase additional modules.
A wizard contains a predefined sequence of steps, which must be passed
through to reach a particular result. In this case, the wizard guides
the user through the steps of preparing a calibration model. The user
has the following opportunities to navigate within the wizard:
Why are some buttons inactive in the wizard?
Navigation items like buttons are only active, if all required conditions
are fulfilled to proceed to the desired step. If not, please check the
contents of the current wizard step.
Proceeding to the next step
By clicking the Next > button,
you will move one step forward in the wizard.
Proceeding to the previous step
By clicking the < Back button,
you will move one step back in the wizard.
Aborting the calibration wizard
To abort the current calibration without saving, press the Cancel
button or just press the ESC-key.
Finishing a calibration
When all steps have been accomplished successfully, the Finish
button will become active. Click this button to save the calibration and
leave the calibration wizard.
