The Calibration Curve

The Calibration Curve method window allows you to evaluate the calibration. For more information about the calibration, refer to Theory of Calibration  Calibration (Overview).

• Open the window from a different method, for example, from the Integration window, by selecting Show Calibration Curve on the View menu.

• Or, click the corresponding icon on the toolbar.

As described for the QNT Editor and Integration methods, various window sections can be displayed. The window arrangement usually comprises the Chromatogram, Calibration curve, and Report windows.

• Press F4 or SHIFT+F4 to change to the chromatogram of a different sample. Generally, all chromatograms of a sequence can be displayed on after the other.

• In the chromatogram, select the peak for which you want to display the calibration curve. The peak’s background color changes.

• The Calibration tab page of the Report window shows the most important calibration data, such as Calibration Type, number of calibration points,  Relative Standard Deviation (Rel.Std.Dev), Correlation Coefficients as well as the following calibration coefficients: Offset (c0), Slope (c1), Curve (c2), and Cubic Coefficient (C3). In addition, you can display, for example, the Variance or Standard Deviation (Std.Dev).

• Select Decoration on the context menu to change the colors and the captions of various window elements.

• Select Column Properties or Table Properties on the context menu to change the contents and the layout of the table. For more information, refer to  Creating and Using Report Tables.

For more information about the calibration curve, refer to  Displaying Calibration Curves.

 Note:

We would like to point out that the default use of the report variables in the Integration, Calibration, and Peak Summary reports is not binding in Chromeleon. You can freely configure each of the three reports, use any variables, or rename the report as desired.
