Abstract
Sample preparation is an integral
and perhaps the most important step in chemical analysis. However, current
techniques employed for preparing samples are multi-step, laborious, expensive,
and often unreliable. Therefore, a need remains for solvent free or solvent
minimized microextraction devices that permit the acquisition of low
concentrations of analytes present in a wide range of aqueous or other liquid
environments.FIU inventors have developed
in-vial microextraction (IVME) method and IVME devices that are sample
collection vials. These vials have a sorbent coating on at least a portion of
the inner surface of the vial, and a sorbent coating of the same of different composition
on at least a portion of the outer surface of the vial. The sorbent coating are
constructed on the surface of the vial using sol-gel coating technology, and
comprise metal oxide comprising gels that are capable of absorbing at least one
target analyte. These vials can be of different size, shape, and construction
materials.
Benefit
Enables both sampling and sample preparation in the field Permits the acquisition of low concentrations of analytes present in a wide range of aqueous or other liquid environments Can be used by untrained individuals to provide truly representative sample Allows the work up of the samples in a simple and effective manner
Market Application
Sample preparation for a wide variety of analytes in various fields such as biological, environmental, clinical, toxicological, food, pharmaceutical, bio-analytical, and forensic.
