Replacement Information Replacement Information 1.13187.0001 replaces and is identical to 13187-1 重要规格表
描述 产品目录编号 113187 Replaces 13187-1; 13187 同义词 13187-1, 13187 描述 HPTLC Silica gel 60 F₂₅₄ with concentrating zone 5 x 2.5 cm 概述 These plates allow users to quickly and easily apply any kind of sample, even large volumes of diluted samples. Our concentrating zone plates are based on different adsorption properties of two adsorbents. The first is a large pore concentrating adsorbent where the samples are applied; the second is a selective layer for separation. Regardless of the spots’ shape, size, or position, the sample always concentrates as a narrow band where the two adsorbents overlap and where the separation starts. These plates allow users to quickly and easily apply any kind of sample, even large volumes of diluted samples. 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 layer thickness concentrating zone 70 - 110 µm Fluctuation in the thickness of the concentration zone ≤ 35 µm Chromatographic testing:
