Extract

Several correction algorithms (Lachance & Traill (L-T), Rasberry & Heinrich (R-H), Lachance & Claisse (L-C) and Claisse & Quintin (C-Q) have been inter compared. All these algorithms assume that the effects of the matrixelements can be added in a linear way. Tertian, however, has shown that this is perfectly valid only when absorption is the only interelement effect to be taken into account. When enhancement is involved, corrections for crossed-effects are necessary. We have also evaluated the application of crossed-effect correction. Calculations were done, using theoretically calculated relative intensities. Influence coefficients were calculated by a regression method.
