In-Vial Microextraction Systems – IP 1607

Sample preparation is an integraland perhaps the most important step in chemical analysis. However, currenttechniques employed for preparing samples are multi-step, laborious, expensive,and often unreliable. Therefore, a need remains for solvent free or solventminimized microextraction devices that permit the acquisition of lowconcentrations of analytes present in a wide range of aqueous or other liquidenvironments. FIU inventors have developedin-vial microextraction (IVME) method and IVME devices that are samplecollection vials. These vials have a sorbent coating on at least a portion ofthe inner surface of the vial, and a sorbent coating of the same of different compositionon at least a portion of the outer surface of the vial. The sorbent coating areconstructed on the surface of the vial using sol-gel coating technology, andcomprise metal oxide comprising gels that are capable of absorbing at least onetarget analyte. These vials can be of different size, shape, and constructionmaterials. Anne Laure Schmitt Olivier aschmitt@fiu.edu 305-348-5948
