Novel Composite Monolith as a New Solid Phase Extraction Material for Environmental Analysis


University of Alberta researchers have developed a new material of a composite silica monolith nested in sponge (SiMNS) for solid phase extraction. The application of the new SiMNS material has been demonstrated in trace analysis of environmental contaminants in water. The material is mechanically flexible and allows for production of solid phase extraction cartridges of desirable sizes and shapes without frits. The surface properties of SiMNS can be fine-tuned for applications in environmental, food and biological analysis in a cost-effective manner.
