An important factor that can affect the intensity ratio of chemical components, e.g. Al2O3, is chromatic aberration of the objective lens [1]: To eliminate
chromatic aberration at an energy loss [1]: Measuring the intensity this way described above minimizes the effects of chromatic aberration on the measured ratio.
