EMD Millipore 1.15647.0001 Glass Backed HPTLC Modified Plate, 200µm Thick Silica Gel 60 NH2 F254s, 10cm Width, 10cm Length (Pack of 25)

The amino-modified silica NH2 plates provide weak basic ion exchange characteristics. These unique features enable the separation of charged compounds such as nucleotides, purines, pyrimidines, phenols and sulfonic acids using simple eluent mixtures. In addition, NH2 modified silica plates allow for reagent-free etection of certain chemical substances by thermochemical fluores-cence activation. Because most substance separated on these modified plates are colorless, our modified plates contain the blue fluorescing, acid stable UV indicator F254s. Samples which absorb short-wave UV at 254 nm are detected due to fluorescence quenching.
