Examples were provided of a wide range of techniques for the sampling and analysis of reactive materials, or materials which can undergo further reaction either with themselves or with another material or compound under environmentally mediated conditions. Specific topics included in this review were impinger sampling, specialized storage techniques, reagent coated sorbents, and direct reading instruments. The integrity of the reactive material under study has been protected by specialized storage techniques such as the use of inert sorbents, storage at low temperatures or in the dark, and the application of stabilizer coatings on sorbents. A sorbent could be designed for a particular reactive compound. The development of portable, direct reading instruments rendered it possible to conduct analyses of reactive materials where they exist in the workplace. Advantages of these newer methods included better sample stability, increased sampling and analytical sensitivity, increased analyte specificity, ease of sampling, reduced need to handle toxic or carcinogenic compounds, better precision and accuracy, and simultaneous analysis of multiple compounds. Disadvantages included the need for more highly skilled analysts, the higher cost of specialized reagents, sorbents and analysis techniques, longer analysis times, more labor intensive sample preparation, and the lack of commercially prepared sampling devices.
