基本信息
| General description【一般描述】 | Our NH2, CN and DIOL -modified silica sorbents are less polar then conventional silica phases, making them ideal for separating hydrophilic or charged substances. Our moderately polar cyano- and diol-modified silica plates can be used for both normal phase and reversed phase systems. An alternative to PEI cellulose, amino-modified NH2 plates provide weak basic ion exchange characteristics with special selectivity for charged compounds. 25 Glass plates 20 x 10 cm |
| Analysis Note【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: ≤ 35 µm Chromatographic testings: A) Steroidtest, straight phase hRf-values - hydrocortisone, straight phase: 4 - 8 - Reichstein S, straight phase: 11 - 18 - Methyltestosterone, straight phase: 27 - 36 B) Steroid test, reversed phase - methyltestosterone, steroid test: 48 - 68 - Reichstein S, steroid test: 58 - 78 - hydrocortisone, steroid test: 68 - 88 Typical value determined on an activated plate (120°C, 15 min) Eluent a) petroleum benzine 40-60°/acetone (80/20 v/v) Eluent b) acetone/water (30/70 v/v) |
