Popis: A new liquid chromatographic technique for the separation of the anticancer drug cisplatin, its trans isomer, and their corresponding cytotoxic hydrated complexes is presented. The separation is performed on porous graphitic carbon using an alkaline aqueous phase, where the hydrated complexes are present in their less reactive, uncharged form. The electrospray mass spectrum of cisplatin differed from that of transplatin, giving a sodiated adduct ion. The monohydrated complex of cisplatin showed [M - H 2 O] + , M + , and [M - H 2 O + MeCN] + clusters starting at m/z 263, 281, and 304, respectively, using a solvent mixture containing acetonitrile. The identity of m/z 304 was established by MS/MS.
