Abstract

An in-vial microextraction (IVME) device is a vial with at least a portion of the inner surface having a sol-gel coating that absorbs at least one target analyte. The sol-gel coating is a metal oxide comprising coating that is formed from a tri- and/or tetra-functional metal comprising precursor that condenses to form a gel network. The IVME device can be used to prepare a sample by the contacting of the IVME device with a solution or suspension. An analytical method is enabled where the absorbed analyte from the IVME device is subsequently desorbed with a solvent or solution or thermally desorbed and analyzed using GC-MS or LC-MS or other analytical instrument for separation and detection.
