Fluorinated Monolithic Columns for LC

Researchers from Queen's University (Kingston, Ontario, Canada) developed porous polymer capillary columns with varied flurous content for chromatography of tagged analytes.

Researchers from Queen's University (Kingston, Ontario, Canada) developed porous polymer capillary columns with varied flurous content for chromatography of tagged analytes. They used a UV-initiated radical polymerization process to create the monolithic columns and tested them using flow-induced back pressure and scanning electron microscopy. The columns were able to separate fluorous-tagged analytes under gradient conditions, and the researchers found that the fluorinated monolithic columns exhibited greater selectivity for fluorous analytes than did comparable nonfluorinated monolithic columns.
