Two-dimensional HPLC analysis of oligostyrenes: Comprehensive and online heart-cutting techniques

2-D HPLC incorporating two reversed phase (RP) environments was employed for the isolation of oligomers and their diastereomers of low molecular weight oligostyrenes. The operation of a comprehensive method of analysis was compared to a heart-cutting approach.

Preparation and HPLC application of chiral stationary phase from 4-tert-butylphenylcarbamates of cellulose and amylose immobilized onto silica gel

The 4-tert-butylphenylcarbamates of cellulose and amylose bearing a small amount of 3-(triethoxysilyl)propyl residues were synthesized by a one-pot process and efficiently immobilized onto a silica gel through intermolecular polycondensation of the triethoxysilyl groups.
