| titleOfInvention | Method and silicate composition for conditioning silica surfaces |
| abstract | Disclosed is a method for increasing the electroosmotic flow rate available for a silica surface. In the method, there is provided an electrophoretic channel which is defined by one or more silica surfaces. The surfaces) are contacted with an alkaline aqueous solution containing a solubilized silicate-monovalent metal complex in an amount effective to increase the acidity of the silica surfaces(s), as evidenced by a reduction in the average bulk pKa of the surface(s). The achieved increase in acidity is greater than would be obtained using an otherwise identical solution lacking said silicate. In one preferred embodiment, the monovalent metal used in the solution is Li+, Na+, or K+. Also disclosed is a method for increasing the acidity of a silica surface, by contacting the surface with an alkaline aqueous solution of the type noted above. |
