摘要： Described are devices, systems, and methods directed to extraction columns. An embodiment of the extraction column includes a column body having a reservoir portion including an inlet and a reservoir, an extraction media portion, and a collar portion. The extraction media portion includes an elongated sleeve having a cavity having an extraction medium disposed therein. The extraction media portion has an inlet end and an outlet end. The collar portion extends axially 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. Also described is a sheath with a medium disposed therein, wherein the medium is separated from an inner surface of the sheath by a layer configured to substantially prevent a portion of sample from bypassing the medium.
