一般描述 100 Glass plates 2.5 x 7.5 cm Our classical silica TLC plates are based on a combination of our proven silica gel 60 and the addition of a unique polymeric binder resulting in a very adherent and hard surface that will not crack or blister and even allow writing with a pensil on the surface without risk to damage the layer. Replaces: 15326-1; 15326 分析说明 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): 9.5 - 11.5 µm Layer thickness: 210 - 270 µm Deviation of layer thickness per plate: ≤ 35 µm Chromatographic testing: colour test hRf-values - bleu vif organol, colour test, lipophile: 11 - 25 - Ceres Black G, colour test, lipophile: 34 - 48 - ceres Violet brn, colour test, lipophile: 52 - 67 separation number (colourtest, lipophile): ≥ 9.0 Typical value determined on a conditioned plate Eluent: toluene (45% rel. humidity) 物料 glass support silica gel 60 matrix 质量水平 100 特点 binder Organic Polymer fluorescent indicator: no 包装 pkg of 100 plates technique(s) thin layer chromatography (TLC): suitable 层厚度 250 μm 板长度 × 宽度 2.5 cm × 7.5 cm 粒径 10-12 μm 孔径 60 Å medium pore diameter 储存温度 2-30°C
