✦ Synopsis
A new bulk matrix correction program for quantitative electron probe microanalysis based on a double Gaussian u(qz) approach is presented. The independent input parameters for this new model are a (decay rate in the righthand Gaussian), surface ionization u(0), peak position and integral of u(qz) (FI). The Gaussian exponent in (qz m ) the left-hand branch (b) is calculated through an iterative procedure. The resulting program is completely modular in structure, which means that all vital independent input parameters can freely be changed without disrupting the mathematical functioning of the model. The increased Ñexibility of this new model (PROZA96) leads to superior performance over its predecessor (PROZA), especially for the analysis of ultra-light elements.
