描述 产品目录编号 105548 Replaces 5548-7; 5548 同义词 5548-7, 5548 描述 HPTLC Silica gel 60 F₂₅₄ 概述 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. 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 ≤ 30 µm Chromatographic testings:
