描述 产品目录编号 105914 Replaces 5914-6; 5914 同义词 5914-6, 5914 描述 HPTLC Silica gel 60 RP-18 概述 RP modified plates serve two purposes: act as a pilot method for HPLC and allow to choose various solvent system for special separations. Our RP-modified silica layers are well suited for many separation challenges that unmodified silica cannot overcome. These layers use aqueous solvent systems to separate extremely non-polar substances and analyze particular polar substances that can adapt to ion-pair chromatography. What’s more, RP-modified silica layers are less dependent on atmospheric humidity. Unlike unmodified silica, RP-phases do not exhibit catalytic activity. This makes them the plates of choice for unstable substance that tend to experience oxidative degradation. 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 testings:
