Field sampling kit for chemical recovery, storage, and profiling, method of making and using the kit, and dynamic fabric phase sorptive extraction (DFPSE) medium

摘要

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.

1. A dynamic fabric phase extraction (DFPSE) device, comprising: a plurality of stacked fabric phase extraction (FPSE) layers, wherein at least one of the FPSE layers is an analyte absorbing FPSE layer comprising at least one analyte absorbing FPSE medium; and at least one barrier FPSE layer on a top and/or bottom surface of the DFPSE, and wherein the analyte absorbing FPSE medium comprises a fabric substrate with a sol-gel coating that selectively absorbs a cationic analyte, anionic analyte, acidic analyte, basic analyte, polar organic analyte, or non-polar organic analyte.
