Application

Ucon HTF 14 is a thermoseparating polymer (TSP) that can be used in aqueous two-phase extraction (ATPE) due to its decreasing solubility in its aqueous solution as the temperature rises. It is also used in a polymer coating on solid-phase microextraction (SPME) fibers using the sol-gel technique to impart thermal resistance and stability.
