Popis: A fabrication method of molding-type solid-phase extraction media (M-SPEM) bound with commercially available adhesive is presented. Six pieces of M-SPEM were prepared by heating each kneaded product of a particulate sorbent and an adhesive inserted into a six-hole cylindrical mold for hardening under an open system and normal pressure. The particulate sorbent contained in M-SPEM was divinylbenzene-based reversed-phase mode solid-phase extractants that we have reported. An examination of several adhesives showed that the moldability of M-SPEM depended on the composition and properties of the adhesive. The optimized procedure can be used to prepare an M-SPEM containing an 85 wt% particulate sorbent (particulate sorbent/adhesive, 100 mg/17 mg; particle diameter, 90-150 µm), and the M-SPEM has a specific surface area of about 500 m
