Facts About Column Engineering Although there are many distributors of columns and packing materials for HPLC, few bond their own packings and fewer still actually manufacture a silica bead from starting raw materials. The truth is that most column suppliers will not admit this or will make you believe that they are making their own materials. Making and bonding base material gives complete control of quality and consistent performance characteristics. Since 1981 column Engineering has been a supplier of packing materials to several prominent columns manufacturers.
