Concentrator materials of choice are often polymers. Polydimethylsiloxane (PDMS), or a polydimethylsiloxane/divinylbenzene copolymer (PDMS/DVB) are favored choices for explosive molecules. PDMS are often used in the form of solid-phase microextraction (SPME) fibers. PDMS/DVB is often used in the form of microspheres with diameters in the 50- to 75-pm range. Detailed considerations for use of SPME fibers is given on a website maintained by the University of Western England [19], It references a more complete treatise [20], Other geometries, such as stacked spheres, have also been used successfully [21],... 

During the 1990s, there has been much activity in polymerization, scientific studies, and application development related to PVDF. Many copolymer variations and compounds of PVDF have been introduced by the polymer manufacturers and their immediate resin customers. This article will reference selected recent scientific and technology advances and focus upon property profiles and uses of the various PVDF grades available. A prior encyclopedia article (3) provides extensive references to the earlier studies. Detailed information on the properties and applications is given by the PVDF manufacturers at their websites. When the term pvdf is used to search the Chemical Abstracts databases from 1992, there are approximately 500 citations per year, about half of which are patents. Hence, the freedom to operate or utilize PVDF in any application by a new user should be verified by a careful check of the patent literature. In addition, producers of PVDF should be consulted regarding proposed medical applications, especially related to body invasive or implant technology.
