I need to analyse an organomercurial named Thiomersal (Sodium ethylmercurithiosalicylate, C9H9HgNaO2S) and two benzoic acids : thiosalycilic acid (2- Mercaptobenzoic acid , C7H6O2S) and dithiosalycilic acid (2.2' dithiodibenzoic acid, C14H10O4S2). I've been using a RP18 colunm with methanol/water, but I have dificulties separating the 3 compounds. I would like to know if anybody has experience with this thype of compounds and can give me some hints.
Tks

Try to control and/or adjust the pH!
