Aluminium oxide TLC plates
For basic and neutral compounds using different pH conditions
Aluminium oxide plates provide distinct separation advantages with regard to the pH: under aqueous conditions, basic compounds can be best separated on basic aluminium oxide plates, while neutral compounds are best separated on neutral plates. EMD Millipore TLC aluminium oxide plates utilize neutral or basic aluminium oxide with 60 Å or 150 Å pore size with or without fluorescent indicator to suit different application needs.
