Polymer microcolumn for gas or vapor separation, chromatography, and analysis

Kenneth S Suslick (Inventor), Jordan J Hinman (Inventor)

Research output: Patent


In an aspect, a method for forming a microcolumn comprises steps of: (a) providing a sacrificial fiber; (b) forming a microcolumn body around said sacrificial fiber; and (c) removing said sacrificial fiber from said microcolumn body such that a hollow channel is formed within said microcolumn body via removal of said sacrificial fiber. In any embodiment of the methods disclosed herein for forming a microcolumn, said hollow channel extends through said microcolumn body and is continuous between a first end and a second end. The first end may be an inlet and the second end may be an outlet, for example, allowing for a mobile phase to enter the hollow channel via the first end and exit via the second end.
