Solid Supports for Sorptive Thin Films
Background
Sorptive Thin Films have found broad applicability as a separation method that allows for the isolation of organic molecules from aqueous samples, air and semisolids. In the field of analytical extractions, sorptive thin films are applied to techniques such as Thin-Film Solid Phase Microextraction (SPME) and Fabric Phase Sorptive Extraction (FBSE), which have greatly improved extraction performance and throughput over traditional arrow and fiber technologies and dispersive or flow-through extraction methods. Current film holders present technical challenges either by releasing the film during vigorous extraction or bending the film, resulting in lost time and poor precision. This invention aims to overcome the limitations of current holders by providing a solid and uniform grip on the thin film that allows for higher agitation speeds, avoids bending of the film, and promotes uniform mass transfer of the molecule onto the sorbent for extraction. This invention can also be used beyond the scope of analytical extraction to test mechanical properties of thin films and conduct fouling studies.
Invention Description
Researchers at the University of Toledo have developed a series of novel SPME thin film holders allowing for greater extraction and higher throughput without risk of damage to the film.
Applications
-Thin Film SPME where throughput and ease of use are paramount.
