一般描述 HPTLC plates deliver fast and quantitative analysis of complex samples for manual or automated use. Our HPTLC silica plates work three times faster than conventional TLC plates – and they are more sensitive. The particle sizes range in HPTLC is between 4-8 µm, which creates a smoother surface and a higher separation power than TLC plates. 25 Aluminium sheets 20 x 20 cm Replaces: 5547-7; 5547 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): 5 - 7 µm Layer thickness: 150 - 200 µm Deviation of layer thickness per plate: ≤ 30 µm Chromatographic testing: colour test hRf-values - bleu vif organol, colour test, lipophile: 17 - 22 - Ceres Black G, colour test, lipophile: 38 - 43 - ceres Violet brn, colour test, lipophile: 58 - 64 separation number (colourtest, lipophile): ≥ 10.0 Typical value determined on a conditioned sheet Eluent: toluene (45% rel. humidity) 物料 aluminum support silica gel 60 matrix 质量水平 100 特点 binder Organic Polymer fluorescent indicator: no 包装 pkg of 25 sheets technique(s) thin layer chromatography (TLC): suitable 层厚度 200 μm 薄片长度 × 宽度 20 cm × 20 cm 粒径 5-6 μm 孔径 60 Å medium pore diameter 储存温度 2-30°C
