Résumé(disponible en anglais seulement)
Willis and Lachance [9] debate the pertinence of a recent study done by Rousseau [2] of three "popular expressions" relating concentration to intensity in X-ray fluorescence (XRF) analysis. It should be pointed out that Willis and Lachance debate only the Lachance identity (Eqn 1) and its associated "new" Lachance-Traill algorithm (Eqn 2) and ignore the two other expressions, namely Claisse-Quintin and Broil-Tertian algorithms [2]. They also continue to ignore the fundamental character of the algorithm proposed by Rousseau [1]. The author would like to thank Willis and Lachance to give him the opportunity to debate six of his arguments in a rational and objective way. As a result the XRF analysts will be able to select the most reliable analytical methods, for getting the most accurate results, with full knowledge of the facts. Their choice of a method will not be based only on the reputation of its author... Finally the author discusses the validity of the four last conclusions that were reached by Willis and Lachance.
