EXTRACTION COLUMN

摘要

Described are extraction columns and systems that include extraction columns. The extraction column includes a column body that has a reservoir portion, an extraction media portion, and a collar portion. The reservoir portion includes an inlet and a reservoir. The extraction media portion includes an elongated sleeve having an inner surface defining a cavity. The extraction media portion has an inlet end in fluid communication with the reservoir and an outlet end. An extraction medium is disposed in the cavity of the elongated sleeve. The collar portion extends axially in a common direction with the elongated sleeve. The collar portion has a terminal end which is spaced apart from the outlet end of the elongated sleeve and which extends axially at least to a plane defined by the outlet end of the elongated sleeve.
