Display Calibration Curve Intensities
This menu will display the calibration curve intensities for all standards for each selected unknown or standard sample and the interpolated unknown counts and concentrations for that sample. This is a multi-standard XRF type calibration correction and is extremely useful for certain types of difficult analyses provided that one has standards with appropriate concentrations in a matrix similar to the unknown to be measured. For example carbon in steel alloys.
The ZAF, Phi-Rho-Z, Alpha Factor and Calibration Curve Selections option for Calibration Curve must be selected from the Analytical menu first. Also at least two standards per element are required although only one standard is required if the Use Zero Point For Calibration Curve option is selected in the Analysis Options dialog available from the Analytical menu.
