By characterizing the phase, the behavior of compounds on the phase may be better predicted. One way to characterize the phase is to compare its selectivity against a well- documented column such as DB-1.Gay SunPhil Stremple
The fundamental arrival rate λ of this DBMAP can then be defined as(2)λ=πa∑i=1∞iDie,where πa is the stationary probability vector of D in (1), i.e. πaD = πa, πae = 1, and e is assumed in this paper to be the all-1 column vector with the designated dimension. ...

Complete separation of enantiomers has been achieved on a Chiralcel OD-H analytical column (250 × 4.6 mm) using n-hexane–isopropanol (80:20, v/v) as the mobile phase at a flow rate of 1.0 mL/min under UV and optical rotation detection. The effect of the mobile phase and temperature ...
Althoughthe chromatograms of individual resins and their blends are independentof the cooling rate, it will be shown that sample volume (column loading)and heating rate during the elution cycle affect the peak separationof the components in binary blends.Alghyamah...
Capillary columnPoly-(1-trimethylsilyl-1-propyne) (PTMSP)Modified stationary phaseIn this work, we report the study of properties of capillary columns with a porous layer of the functionalized polymer prepared via oxidation of poly-(1-trimethylsilyl-1-propyne) (PTMSP) by nitrous oxide. It was ...

In this work, the enantioseparations of 1,1′-bi-2-naphthol (BINOL) and its three derivatives were performed on an immobilized polysaccharide-based chiral stationary phase, Chiralpak IA, under normal-phase mode. The effects of the content of polar modifier in the mobile phase and the column ...
