This paper presents a detailed interpretation of the interface saturation data of liquid tin and aluminium drops, on the basis of a mathematical description of the interface evolution described in a previous paper. We also discuss the relevance of evolution times towards the stationary condition for both metal drops, which have given us a better understanding of the interface behaviour and also allowed us to attempt a quantitative estimation of the excess interface concentration.
