A sample storage device comprises a vial provided with an opening, a permeation tube arranged within the vial, permeable to a fluid contained in the vial or the permeation tube, and having a first closed end and an opposite second end, and a septum closure sealing the vial opening. In one embodiment, the permeation tube second end is open, the permeation tube is arranged within the vial with the second end adjacent the vial opening, and the septum closure seals the vial opening and the second open end of the permeation tube. The vial has a sample fluid, at least a portion of which is in contact with an outer surface of the permeation tube, and the permeation tube is permeable to the sample fluid. In a second embodiment, the permeation tube second end is closed, and the permeation tube includes a marker-containing adsorbent therein. The vial has a sample fluid therein and the permeation tube is permeable to the marker. In a third embodiment, the vial has a marker-containing adsorbent therein, and the permeation tube second end is open. The permeation tube contains a sample fluid and is arranged within the vial with the second open end of the permeation tube adjacent the vial opening. At least a portion of an outer surface of the permeation tube is in contact with the marker, and the permeation tube is permeable to the marker. The septum closure seals the vial opening and the second open end of the permeation tube.
