Interpolation analysis

Plot the observation data of the Standard sample and the Test samples, calculate the standard curve and determine the unknown concentration by interpolation on this curve.

Example

The following image from the 'Linear calibration curve (enhanced response data processing)' sample document shows results for Test sample TST4, with response data being adjusted by a fixed value of '1'.

The following image from the '4PL calibration curve' sample document shows results for Test samples TST1, TST5, and TST8. Response values are interpolated on a calibration curve. The interpolation results are displayed in a data plot and as a table.
The sample document has been enhanced as follows:

For better readability of the resulting interpolation plot, a subgroup has been added to the sample document, with the three Test samples being assigned to it.
An additional Sample suitability test has been defined for Test sample TST8.
An additional predilution factor has been assigned to Test sample TST8, resulting in the calculated working concentration and the calculated absolute concentration to differ from each other by this factor.
