Technical note 1. Candys

MonoTrapTM is a silica-based adsorptive. This product can be characterized by through pour (due to the monolith structure of the silica base) and a large surface (due to the pores within the silica frame). Active carbon is used as an adsorptive on the silica frame surface to which octadecyl (ODS) group has been conjugated. MonoTrapTM can be viewed as a new hybrid adsorptive having a large surface area and possessing the features of silica gel, active carbon and ODS group.
