Evaluation and Application of Stationary Phase Selectivity for Drug Analysis [PDF]

open access: yes
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 ...

Stationary phases based on the nanoparticles for pharmaceutical and biomolecule separations [PDF]

open access: yesNanochemistry Research, 2021
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]

open access: yesAsian Journal of Mathematics, 2004
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.
