Can anyone tell me, if it is possible to obtain the equation for the calibration curve in Chromeleon 6.8? I cannot find it, and I want to test that it quantitates the unknowns correctly.
Thank you in advance.

In each calibration, a mathematical relationship is established between the Amount of a standard sample f(A) and the corresponding area value (A). Depending on the location of the Calibration Points, the relationship can be linear or non-linear (for example, a parabola). Select the Calibration Type and by that determine the shape of the calibration points. The corresponding mathematical functions are called calibration functions.
The value of the corresponding calibration coefficient (c0, c1, c2, or c3) describes the slope of the straight line (linear course) or the shape of the curve (non-linear course). The coefficients are calculated by simply replacing known amount and area values in the corresponding calibration function (standard sample). If c0, c1, c2, and c3 are known, it is also possible to calculate the amounts for an unknown sample.
All variables are fully reportable!
All information can also be found in the Chromeleon Help.
