What is claimed is: 1. A chromatography marker-containing sample storage device, comprising: a vial provided with an opening, the vial having a sample fluid contained therein; a permeation tube having a first closed end and an opposite second closed end, the permeation tube being arranged within the vial and including an adsorbent material therein, the adsorbent material having a chromatography marker adsorbed thereon, the chromatography marker comprising methane, the permeation tube being permeable to the chromatography marker such that the sample fluid contains a quantity of the chromatography marker therein; and a septum closure sealing the vial opening. 2. A sample storage device according to claim 1, further comprising a collar provided around the second end of the permeation tube and securing the second end of the permeation tube in the opening of the vial. 3. A sample storage device according to claim 2, wherein at least one of the collar and the second end of the permeation tube has a chamfered edge extending into the permeation tube. 4. A sample storage device according to claim 2, wherein the collar is formed of a natural or synthetic plastic or elastomer. 5. A sample storage device according to claim 1, wherein the septum closure comprises a removable crimped septum cap. 6. A chromatography marker-containing sample storage device according to claim 1, wherein the permeation tube is formed of a polymer selected from the group consisting of polytetrafluoroethylene and fluorinated ethylene propylene polymer. 7. A chromatography marker-containing sample storage device according to claim 1, wherein the fluid sample contained in the vial comprises a volatile organic compound. 8. A chromatography marker-containing sample storage device according to claim 1, wherein the adsorbent comprises carbon black. 9. A chromatography marker-containing sample storage device, comprising: a vial provided with an opening, the vial having an adsorbent material therein, the adsorbent material having a chromatography marker comprising methane adsorbed thereon; a permeation tube having a first closed end and an opposite second end, the permeation tube containing a sample fluid and being arranged within the vial with the second end of the permeation tube adjacent the vial opening and at least a portion of an outer surface of the permeation tube being in contact with the chromatography marker, the permeation tube being permeable to the chromatography marker such that the sample fluid in the permeation tube contains a quantity of the chromatography marker therein; and a septum closure sealing the vial opening and the second end of the permeation tube such that access to the sample fluid containing a quantity of the chromatography marker in the permeation tube may be obtained via a septum in the septum closure. 10. A sample storage device according to claim 9, further comprising a collar provided around the second end of the permeation tube and securing the second end of the permeation tube in the opening of the vial. 11. A sample storage device according to claim 10, wherein at least one of the collar and the second end of the permeation tube has a chamfered edge extending into the permeation tube. 12. A sample storage device according to claim 10, further comprising a capillary tube extending from outside the vial through the collar into the vial. 13. A sample storage device according to claim 9, wherein the permeation tube is formed of a polymer selected from the group consisting of polytetrafluoroethylene and fluorinated ethylene propylene polymer. 14. A sample storage device according to claim 9, wherein the fluid sample comprises a volatile organic compound. 15. A sample storage device according to claim 9, wherein the adsorbent comprises carbon black.
