Macroporous Polyacrylamide/Poly(ethylene glycol) Matrixes as Stationary Phases in Capillary Electrochromatography
Abstract
A one-step method is described for in situ preparation of macroporous polymeric matrixes to be used as stationary phases for capillary electrochromatography. The monomers (acrylamide, bisacrylamide, and acrylic or vinylsulfonic acid), including hydrophobic ligands (C 4, C 6, or C 12 ), and poly(ethylene glycol) have been polymerized in formamide (or N -methylformamide) aqueous solutions inside the capillary. The capillary wall had been activated first by a bifunctional reagent, to couple covalently the resulting gel inside the fused-silica tubing. Thus, no frit is necessary to keep the stationary phase in place. High efficiencies were obtained for a mixture of alkyl phenones (up to 398 000 plates/m). Good separations are achieved in less than 5 min. The migration time reproducibility is better than 1% (RSD) from run to run and 2.5% from day to day. The gel is stable up to at least 50% acetonitrile used as a mobile phase. On-column UV and fluorescence detection can readily be employed. Applications to peptides and carbohydrates are also shown.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
