However, compounds with basic or acidic characteristics are often difficult to separate using bare silica gel. Though AMINO and DIOL media have been developed for compounds that have basic separation difficulty, there is not yet a proper media to separate acid compounds with carboxyl group, for example. Fuji Silysia Chemical Ltd. developed an appropriate separation, Chromatorex ACD Silica, for acidic compounds by introducing COOH and SO3H bonds on the silica surface (patent applied). Normal Phase Bare & Bonded Silica grades The ACD Silica grades complete the normal phase bare and bonded silica of Fuji Silysia Chemical. For the separation of organic compounds by normal phase liquid chromatography, it is necessary to select the proper media based on its characteristics: Neutral compounds are well separated by bare silica gel. NH silica and DIOL silica are used for basic compounds separation. Now acid compounds can be separated with our new ACD Silica.
