Polymer entrapment in polymerized silicate for preparing highly stable capillary coatings for CE and CE-MS.

An easy-to-implement capillary coating strategy based on polymer entrapment in the network of polymerized silicate is described. In this manner, cationic polymers are tightly fixed onto the inner wall of the capillary for electroosmotic flow control without necessitating complex surface modification chemistries. The resulting coated capillary exhibited good… CONTINUE READING
