基本信息
| General description【一般描述】 | 25 Glass plates 10 x 10 cm 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. |
| Application【应用】 | Glass HPTLC Silica gel 60 NH₂F₂₅₄s plates. Silica gel HPTLC plates size 10 x 10 cm, 25 sheets. |
