CN-, Diol-, NH2- Modified Silica Plates (TLC and HPTLC)
These plates tackle extraordinary separation challenges. Our 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. Most modified plates contain F254s, the blue fluorescent, acid stable UV indicator. Fluorescence quenching is used on samples that absorb shortwave UV at 254 nm.
