EMD Millipore 1.05533.0001 Aluminium Backed TLC Modified Plate, Silica Gel 60, 20cm W x 20cm L (Pack of 20)

CN-, Diol- and NH2-modified silica sorbents are less polar than the classical silica phases and therefore well suited for separation of hydrophilic or charged substances. The CN-modified plate is based on a silica gel 60 modified with a cyanopropyl group while the diol-modified plate utilizes a silica surface modified by a vicinal diol alkyl ether. These moderately polar plates with their intermediate properties fill a gap in the range of the silica plates allowing use in both normal phase and reversed phase systems. Due to their special features, all kinds of solvent systems can be used. Especially the dual personality of the silica-CN plate allows unique two-dimensional separations to be achieved by using the normal phase mechanism in the first direction followed by the reversed phase mechanism in the second direction. 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.
