Merck-Supelco货号581515-U色谱柱Ascentis Si HPLC上海睿安生物13611631389
Ascentis® Si(5 µm) HPLC Columns
L × I.D. 25cm✕21.2mm,HPLC Column
说明
一般描述
Ascentis 系列色谱柱是 Supelco 科学家推出的第四代 HPLC色谱柱技术。Ascentis 系列色谱柱是以高纯硅胶为基质，孔径 100Å，硅胶粒径为 3、5和1 微米。该色谱柱用于小分子的应用，柱内径可从微径柱(1.0mm内径)扩展到制备尺寸(50mm内径)。该系列包括C18、C8、苯基、Si和内嵌极性基团相(反相酰胺)。
Ascentis Si是具有高载样量和优良峰形的硅胶柱。Ascentis Si在正相和HILIC/ANP(水性正相)模式下都可使用。

Characterization of Ascentis RP-Amide column: Lipophilicity measurement and linear solvation energy relationships.
Deborah Benhaim et al.
Journal of chromatography. A, 1217(1), 65-74 (2009-11-27)
This study investigates lipophilicity determination by chromatographic measurements using the polar embedded Ascentis RP-Amide stationary phase. As a new generation of amide-functionalized silica stationary phase, the Ascentis RP-Amide column is evaluated as a possible substitution to the n-octanol/water partitioning system
Shell and small particles; evaluation of new column technology.
Szabolcs Fekete et al.
Journal of pharmaceutical and biomedical analysis, 49(1), 64-71 (2008-11-29)
The performance of 5 cm long columns packed with shell particles was compared to totally porous sub-2 microm particles in gradient and isocratic elution separations of hormones (dienogest, finasteride, gestodene, levonorgestrel, estradiol, ethinylestradiol, noretistherone acetate, bicalutamide and tibolone). Peak capacities

Analytical chemistry, 80(9), 3285-3290 (2008-03-18)
A new method for the simultaneous determination of ozone and carbonyls in air using a two-bed cartridge system has been developed. Each bed consists of reagent-impregnated silica particles. The first contains trans-1,2-bis-(4-pyridyl) ethylene (BPE) while the second contains 2,4-dinitrophenylhydrazine (DNPH).
