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 systemShell 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"Dilute & shoot" approach for rapid determination of trace amounts of nicotine in zero-level e-liquids by reversed phase liquid chromatography and hydrophilic interactions liquid chromatography coupled with tandem mass spectrometry-electrospray ionization.Paweł Kubica et al.Journal of chromatography. A, 1289, 13-18 (2013-04-04)Two analytical procedures are proposed where HILIC and RPLC techniques are coupled with tandem mass spectrometry detection for rapid determination of trace amounts of nicotine in zero-level liquids for electronic cigarettes. Samples are prepared on the basis of the approachSimultaneous determination of ozone and carbonyls using trans-1,2-bis(4-pyridyl)ethylene as an ozone scrubber for 2,4-dinitrophenylhydrazine-impregnated silica cartridge.Shigehisa Uchiyama et al.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).Characterization of new types of stationary phases for fast liquid chromatographic applications.Szabolcs Fekete et al.Journal of pharmaceutical and biomedical analysis, 50(5), 703-709 (2009-06-30)The performance of a narrow bore silica based monolith column (5 cm x 2 mm) was compared to 5 cm long narrow bore (internal diameter < or = 2.1 mm) columns, packed with shell particles (2.7 microm) and totally porous
