1. A method for extracting an analyte from a sample, the method comprising:
introducing a sample into a capillary that comprises an adsorbent material that coats a portion of walls of the capillary;
interacting the sample within the capillary with the adsorbent material within the capillary such that at least one analyte is extracted from the sample and binds to the adsorbent material;
introducing an extraction solvent into the capillary while the sample is still present in the capillary; and
interacting the extraction solvent with the adsorbent material in order to elute the at least one analyte from the adsorbent material, wherein the extraction occurs via iterative back and forth movement of the capillary to results in the adsorbent material interacting with the sample and the extraction solvent over multiple occurrences.
