Analytical separations using molecular micelles in open-tubular capillary electrochromatography
(2002)Open-tubular capillary electrochromatography (OT-CEC) is an alternative approach to conventional CEC. The primary advantage of OT-CEC is the elimination of problems associated with frits and silica particles in conventional ...

Chiral separations using a polypeptide and polymeric dipeptide surfactant polyelectrolyte multilayer coating in open-tubular capillary electrochromatography
(2004)A polyelectrolyte multilayer (PEM) coating consisting of the polypeptide, poly(L-lysine) hydrobromide, poly(L-lysine) and the polymeric dipeptide surfactant, poly(sodium undecanoyl-L-leutcyl-alaninate), poly(L-SULA), is ...

Chiral Separations Using Polymeric Surfactants and Polyelectrolyte Multilayers in Open-Tubular Capillary Electrochromatography
(2003)In this study, fused-silica capillaries are modified using a polyelectrolyte multilayer (PEM) coating procedure in open-tubular capillary electrochromatography. The PEM coating was constructed in situ with alternating ...

Near-monodisperse sodium polymethacrylates: Characterization by linear salt gradient anion-exchange chromatography
(2000)A family of six near-monodisperse homopolymers of sodium methacrylate (Mn = 1100, 3200, 5500, 7200, 14100, and 21000) is characterized by linear salt gradient anion-exchange chromatography. Although the retention times ...

Synthesis and aqueous solution characterization of catalytically active homopolymers, block copolymers and networks containing imidazole
(2000)Imidazole-containing polymers were prepared and characterized in terms of their hydrolytic activity. Unlike similar materials synthesized in the 1960s, the polymers are of precise molecular weight and controlled structure ...
