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.
Claims26
An in-vial microextraction (IVME) device;
- comprising, a vial with at least a portion of the vial's inner surface bonded to a first sol-gel coating and at least a portion of the exterior surface bonded to a second sol-gel coating, wherein the first sol-gel coating is of different composition to that of the second sol-gel coating, wherein the first and second coatings comprise metal oxide comprising gels that absorb at least one target analyte.
An in-vial microextraction (IVME) device;
- comprising, a vial with at least a portion of the vial's inner surface bonded to a sol-gel coating and at least a portion of the exterior surface bonded to a second sol-gel coating, wherein the first sol-gel coating is of like composition to that of the second sol-gel coating, wherein the first and second sol-gel coatings comprise metal oxide comprising gels that absorbs at least one target analyte.
