Solid sorbents, such as Tenax{trademark}, may be used for the collection of complex chemical pollutants. The pollutants are desorbed form the Tenax at the head of a GC column and analyzed by various detectors. Many laboratories pack Tenax into glass tubes of various sizes and shapes. Shipping and storage of both clean and used Tenax cartridges are problematical due to the fragility of the glass tubes. This laboratory provides audit materials for a wide variety of projects, and an optimum shipping and storage system will maintain sample integrity and protect against breakage. Sealing cartridges in a Mylar{trademark} package purged and slightly pressurized with ultra high purity helium provides an inert environment, and helps to maintain sample integrity. The sealed package also provides a protective bubble-like environment perfect for shipping. The preparation method is described and the results of stability studies reported for important indoor air pollutants when compared to traditional storage methods.
