Classic TLC silica plates, GF254 (Silica gel with gypsum as binding agent, fluorescence background at 254nm), 60 Å pore size. Aluminum backed-easily cut by a pair of scissors. What's ideal is that these plates have neutral silica (pH 6-7) instead of the more common acidic silica (pH=5) for TLC silica plates. The neutral silica make the plates compatible with running compounds with an amino group even without the need of adding triethylamine. At the same time non-amino compounds behave the same as on acidic TLC plates. Actual examples performed with the plates have been uploaded for users to see.In listing photo 6 (or below), highly similar diethyl maleate and dimethyl maleate are spotted on the plates and eluted with different ratios of ethyl acetate : hexanes, showing a gradual change of Rf.
