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.

First claim

We claim:

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.

2. The DFPSE device according to claim 1 ; wherein the analyte absorbing FPSE layers and the at least one barrier FPSE layers are combined mechanically, sewn, or adhered to each other.

3. The DFPSE device according to claim 1 ; wherein at least two of the analyte absorbing FPSE layers included for each target analyte to be extracted is disposed between two barrier FPSE layers, wherein the target analytes are selected from the cationic analytes, the anionic analytes, the acidic analytes, the basic analytes, the polar organic analytes, or the non-polar organic analytes, and wherein the FPSE layers of the same type are symmetrically disposed with respect to the center of the DFPSE and the two barrier FPSE layers.

4. A field kit for collection of one or more analytes, comprising:
one or more dynamic fabric phase extraction (DFPSE) devices according to claim 1 and/or one or more fabric phase extraction (FPSE) devices;
a plurality of containers for storing and transporting the DFPSEs and/or FPSEs that were used for sampling;
documentation media, wherein information of the site, quantity, date, and other pertinent information concerning the sampling can be collected and maintained with the samples acquired using the kit.

5. The field kit according to claim 4 , further comprising a holder for fixing one or more of the DFPSEs and/or one or more of the FPSEs during sampling.

6. The field kit according to claim 4 , wherein the containers comprise an individual container for each analyte absorbing FPSE layer of the DFPSE.

7. The DFPSE device according to claim 1 ; wherein a plurality of different analyte absorbing FPSE layers target a plurality of different target analytes, and wherein the target analytes are selected from the cationic analytes, the anionic analytes, the acidic analytes, the basic analytes, the polar organic analytes, or the non-polar organic analytes.
