Stability and effectiveness of linear polyacrylamide

Studies of coating stability were performed in bare fused-silica capillary tubes (Photonlines, Marly-le-Roi, France) coated with LPA with a total length of 50 cm (effective length: 41.5 cm)×50 µm inner diameter (id). A gas chromatography oven Trace GC (Thermo-Electron Corporation, Les Ulis Courtaboeuf, France) was used to purge the capillary

A fully automated linear polyacrylamide coating and

polyacrylamide coating and regeneration process is described to support long term stability of fused silica capillaries for protein analysis. The stability of the resulting capillary coatings was evaluated by a large number of separations using a three-protein test mixture in pH 6 and pH 3 buffer systems.

Polyacrylamide-Coated Capillaries Probed by Atomic Force

The inner wall surface topography of fused silica capillaries with an inner diameter of 50 μm, coated with linear polyacrylamide layers of different quality, was investigated by atomic force microscopy (AFM). After electropherograms were recorded of a synthetic mixture of proteins in a capillary having a given coating, the capillary was fragmented into many small pieces, and some of the

Improvement of the long-term stability of polyimide-coated

As a consequence, separation efficiency can deteriorate, the capillary ends can clog or break off. To prevent swelling of the polyimide coating, fused-silica capillaries used in CE or CEC were heated at 300 °C for a longer period of time which improved their long-term stability in comparison to raw fused-silica tubing.

Polyacrylamide-based monolithic capillary column with coating

2.2.1 Preparation of polyacrylamide monoliths A fused-silica capillary (75 mmid6365 mm od), which was purchased from Yongnian Optic Fiber Plant (Hebei, China) was used to prepare a polyacrylamide-based monolithic cap-illary column. Briefly, the inner wall of a capillary was pre-vinylized by g-MAPS as described by Dong et al. [38]. The
