描述 产品目录编号 113192 描述 HPTLC Silica gel 60 NH₂ F₂₅₄s 概述 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. 产品信息 HS代码 3822 00 00 GHS安全信息 储存类别 10 - 13 其它液体及固体 规格 规格 Specific surface area (according to BET; 5-Pt. measurement) 480 - 540 m²/g Pore volume (N₂-isotherm) 0.74 - 0.84 ml/g d 50 (laser diffraction, size distribution) 5 - 7 µm Layer thickness 150 - 200 µm Deviation of layer thickness per plate ≤ 35 µm Chromatographic testing:
