Evaluation and Application of Stationary Phase Selectivity for Drug Analysis [PDF]
Despite the wide range of HPLC stationary phases available for reversed-phase high-performance liquid chromatography (RP-HPLC) and the in-depth studies using probes to highlight differences between them, there is very little in the way of stationary ...

Preparation and characterization of poly(l-phenylalanine) chiral stationary phases with varying peptide length. [PDF]
Three new chiral stationary phases with different lengths of l-phenylalanine peptide were prepared by solid-phase synthesis with tert-butoxycarbonyl (Boc)-l-phenylalanine on silica.

Separation of propranolol enantiomers using chiral HPLC [PDF]
Enantiomers of pharmaceuticals may exhibit different effects because the organism serves as a chiral selector. Enantiomers can now be identified and separated using analytical techniques such as gas chromatography and high-performance liquid ...

Stationary phases based on the nanoparticles for pharmaceutical and biomolecule separations [PDF]
Because of impossibility to achieve a general column for separation purposes, columns must be amended in order to acquire specific chemical characteristics such as hydrophobic, hydrophilic or ionic interactions.

Microlocalization and Stationary Phase [PDF]
Let M be a holonomic module over the Weyl algebra K[t], K a field of characteristic zero. We prove a stationary phase formula which expresses the formalization of the germ at infinity of the Fourier transform of M in terms of a sum of local contributions depending on the germs defined by M at its singular points and at infinity.
