More Information
Summary:An article of manufacture is provided that is useful in differentiating between solutes, such as during electrophoretic separations. An embodiment of the article is a capillary tube, that carries a polymer along the inner wall of the capillary tube. The polymer is effective to reduce undesired interactions and preferably include s a polylactam that is absorbed to the surface before the surface is exposed to the solutes. A preferred polylactam is poly(vinylpyrrolidone) with a molecular weight greater than about 1,000,000 daltons (weight-average).
