Technology Profile
Damian Shea, Ph.D., has invented a novel, patent-pending concept for fabricating a mixed-phase polymer passive sampling device as part of the University of North Carolina at Chapel Hill SRP Center. The device, known as the Composite Integrative Passive Sampler (CIPS), measures chronic exposure to and bioavailability of chemicals and their metabolites. Shea also has created a new start-up company, Statera Environmental, Inc. , to develop, market, and distribute this technology.
| Technology | CIPS is composed of a continuous mesoporous sorptive phase embedded in a supporting microfiber membrane that sequesters both polar and nonpolar organic chemicals from water. Invented as part of the UNC Superfund Center, Statera is now developing the device so it can be used to measure the time-weighted average concentration of contaminants, providing a more accurate measure of chronic exposure to a variety of chemicals in water. |
|---|---|
| Innovation | CIPS is a new generation of passive sampling device that will overcome key limitations of competing technologies and revolutionize environmental monitoring for organic chemicals in water, with the potential for further applications in air, soil, and sediment. |
| Contaminant and Media | Over 200 chemicals, including polar and nonpolar organic chemicals, in water. This passive sampling device has been used to measure polychlorinated biphenyls, dioxins and furans, polycyclic aromatic hydrocarbons (PAHs) and PAH metabolites, current-use pesticides and metabolites, antibiotics, and a suite of pharmaceuticals and personal care products. |
