Abstract: A device for extracting an analyte from a sample matrix comprises a sorption cap or closure which is coated on the inside surface with a sorbent material. A method for extracting an analyte from a sample matrix includes exposing the cap sorptive coating to the sample matrix by sealing the sample bottle or vial with the sorption cap. After the analyte is collected in the sorbent material, the sorption cap may be removed from the sample container and used to seal an analytical vial containing a small amount of an elution solvent. The analytical vial with sorptive cap may then be stored or transported to a lab for further analysis.

Abstract: A device and method for extracting an analyte from a sample matrix comprises a sorption liner, which is coated with a sorbent material on the inside surface of the liner. A method for extracting an analyte from a sample matrix includes exposing the liner sorptive coating to the sample matrix by continuously feeding the sample matrix through the liner, or filling the liner with the sample matrix and sealing both ends of the liner. After the analyte is collected in the sorbent material, the sorption liner may be emptied and attached to an analytical device, such as a gas chromatograph. The analyte then undergoes desorption and is fed directly into the analytical device.

Abstract: A sorption pipette tip is disclosed for the extraction of a sample, or analyte, from a sample matrix with a method of using the sorption pipette tip to perform the extraction. The pipette tip has a coating of a sorptive material. The orifice of the tip may have different configurations that enhance extraction. A sample is aspirated into a sorption pipette tip and either allowed to sit for a given period of time, or the sample aspirated into and out of the pipette tip repeatedly, until the compounds of interest, the analyte, are extracted from the sample by partitioning into the sorptive coating. After partitioning of the sample into the sorptive material, the sample is expelled from the pipette tip. The tip may be washed by aspirating with water. An elution solvent is then used to extract the analytes from the sorptive coating. The solvent containing the compounds of interest, the analyte, may be collected from the pipette tip for further chemistry.

Abstract: A device for extracting an analyte from a sample matrix comprises a flow through well plate, each well which is coated with a sorbent material. A method for extracting an analyte from a sample matrix includes exposing the sample to the sorbent coating of the well plate. The sorption-coated well plate retaining the analyte may then be stored or transported to a lab for further analysis.

Abstract: A device for extracting an analyte from a sample matrix comprises a closed well plate, each well which is coated with a sorbent material. A method for extracting an analyte from a sample matrix includes exposing the sample to the sorbent coating of the well plate. The sorption-coated well plate retaining the analyte may then be stored or transported to a lab for further analysis.

Abstract: A device for extracting an analyte from a sample matrix comprises a sorption vial with a conically shaped interior surface, which is coated with a sorbent material. A method for extracting an analyte from a sample matrix includes retaining the sorption vial within a sample vessel with the sorbent coating exposed to the sample matrix contained in the sample vessel. After the analyte is collected in the sorbent material, the sorption vial may be removed from the sample vessel and sealed, or a small amount of elution solvent may be added to the sorption vial before sealing. The sorption vial containing the analyte may then be stored or transported to a lab for further analysis.
