This paper presents the enantioseparation using glucose, cellobiose, lactose and raffinose as chiral selector bonded to silica gel via an arm in HPLC. Surprisingly, they also possess high enantioseparation selectivity, may be used in normal-phase and reversed-phase mode, and there is a big chiral...
Stationary Phase In subject area: Engineering Yeast chronological aging, on the other hand, is defined as the viability over time of a stationary-phase, nondividing culture of yeast. From: Reference Module in Biomedical Sciences, 2014 About this pageSet alert Discover other topics ...
aIn HPLC, separation is achieved through the distribution of the analytes between a stationary phase packed in a column and a liquid mobile phase that is pumped through the column. 在 HPLC 中,分离塞在栏和通过栏被注入的一个明亮移动阶段中通过一个固定阶段之间的 analytes 的分配被完成。[translate]...

Enthalpy-entropy compensation has been investigated in reversed-phase high performance liquid chromatography with octylsilica stationary phase. The compensation temperatures were determined for this system, and the results show that their change with the composition of the mobile phase was almost similar ...
Stationary phase selectivity in RP LCThe retention and selectivity properties of 17 columns for reversed-phase HPLC were characterized using classical Galushko, Engelhardt, and Walters chromatographic tests; homologous alkylbenzene and LFER tests in aqueous acetonitrile and aqueous methanol mobile phases; ...
phaseDSCDRIFTCP-MASNMRThis study describes the silanization/hydrosilation approach to produce a charge-transfer-type stationary phase for HPLC. The synthetic procedure involves the catalytic addition of a 7-(2,3-dihydroxypropyl)theophylline to the silica hydride intermediate via carbonyl groups. ...
(MWCNTs) were layer-by-layer assembled onto silica microspheres to form MWCNTs/SiO2 composites.Characterizations of this stationary phase confirmed that MWCNTs was successfully attached on the silica surface layer-by-layer.The composite was used as a stationary phase in HPLC for the separation of ...
