Classic TLC silica plates, GF254(Silica gel with gypsum as binding agent, fluorescence background at 254nm), 60 A pore size. Aluminum backed-easily cut by a pair of scissors. What's ideql is that these plates have neutral silica(pH6-7)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.
