Abstract
A field kit for collecting analytical samples has one or more dynamic fabric phase sorptive extraction (DFPSE) devices and/or fabric phase sorptive extraction (FPSE) devices and a plurality of containers for storing and transporting the DFPSEs and/or FPSEs that were used for sampling. The field kit has media for documenting information concerning the site, quantity, date, and/or other pertinent information concerning the sampling. Samples can be maintained within the kit for any required period of storage. Sampling can be done once or a plurality of times, such that an initial analysis can be carried out and analysis can be repeated using a portion of a FPSE or with a redundant FPSE that has been stored. The DFPSE device is a sampling device including a plurality of FPSEs, such that a number of different types of analytes can be sampled in different layers of the DFPSE. At least one external surface layer of the DFPSE is a barrier FPSE that restricts solids from underlying layers.
