      DescriptionHPTLC Silica gel 60 DIOL F₂₅₄s
      OverviewOur NH2, CN and DIOL -modified silica sorbents are less polar then conventional silica phases, making them ideal for separating hydrophilic or charged substances. Our moderately polar cyano- and diol-modified silica plates can be used for both normal phase and reversed phase systems. An alternative to PEI cellulose, amino-modified NH2 plates provide weak basic ion exchange characteristics with special selectivity for charged compounds.
