Abstract
Solid phase extraction (SPE) sorbents and liquid chromatography (LC) stationary phases are provided, as well as methods of fabricating the same. The SPE sorbents and LC stationary phases can use microcrystalline cellulose particles as the substrate and sol-gel sorbent coating technology as the polymer/sorbent immobilization technology. The SPE sorbents and LC stationary phases are stable in a pH range of 1-13 and at a temperature of up to 350° C.
