Abstract : This report presents the results of a laboratory evaluation of available resins for their efficiency and reliability for sampling low levels of explosives from water for the purpose of quantitative analysis of the explosives. Thirteen different sorbents were evaluated for eight explosives. After the initial screening studies, the most effective resin for each explosive was selected. Each explosive/resin combination was subjected to precision and accuracy testing to determine the detection limit for the explosive in water and the reliability of the method. Preservation studies were also performed to determine if the explosives degraded on the resins. The data show solid sorbent sampling to be an easy and reliable method for removal and concentration of explosives from water and easily adaptable to GC to HPLC analysis for the explosives. Detection limits for all the explosives in water were less than 10 micro g/L. In general, the Porapak (R or S) resins were superior to the styrene divinylbenzene resins (e.g. XAD-4 or XAD-2) for sampling of explosies in water.
