ABSTRACT
In the late seventies, Dr. Berthod investigated the physicochemical properties of micellar solutions and microemulsions by using electrochemistry [1, 2]. He was also involved in liquid chromatography (LC). After reading the early work of Armstrong on micellar liquid chromatography (MLC) [3,4], Berthod decided to study the modifications of the stationary phase of a chromatographic column exposed to micellar solutions [5, 6]. The results of this study were evaluated by Armstrong himself. This was the starting point of a very fruitful scientific collaboration, which began with the writing of a concerted article on the diffusion coefficient of solutes in micellar solutions [7]. Armstrong and Hinze invited Berthod -at the 1986 ACS National Symposium in New York -to the special session titled Ordered Media on Chemical Separations [8], that they were organizing. There, Berthod met most of the researchers involved in MLC at that time: Armstrong, Cline-Love, Dorsey, Fendler, Hinze, Mullins, Pramauro, Pelizzetti and Sybilska.
