United Science is proud to offer cutting edge custom sensors for emerging persistent organic pollutants. The fluorous sensing membrane incorporated into the sensor is highly selective for perfluorinated contaminants and can discriminate over most all other negative ions. Thus, detection limits rival detection limits achieved with LC/MS/MS. Use the sensor for REACH export compliance or in a regulatory environment. Please download product bulletin for technical specifications. We are selecting a limited number of testing partners for GENZero sensors testing. [...]
Perfluorooctanoic acid (PFOA) is a ubiquitous environmental contaminant that has been found at low concentrations in waste water, drinking water, human blood, and in food. Because PFOA and other perfluorochemicals (PFCs) are bio-accumulative, extremely persistent, and toxic, the EPA has established analytical methods and preliminary health exposure and emission limits. In addition to US regulatory efforts, the EU has renewed its drinking water PFOA directive testing mandate for 2011 and is continuing to gather toxicology data. Furthermore, there are [...]
Xanthate is a collector chemical widely used in the beneficiation of sulfide metals such as copper, lead, etc. We developed an electrode based on fluorous sensing membranes to measure xanthate usage in a flotation cell. Flotation is a solid-solid separations process that selectively separates the desired substance from the undesired waste material. In the case of copper, the ore is ground to approximately 75 microns and is dispersed into water. Collectors selectively react with the copper particles and float, [...]

United Science’s technology is based on >$1M in research conducted at the University of Minnesota over the last 5 years. The “Fluorous” ISE product is differentiated from other ISEs in that it has been tested in complex mining solutions and has ideal characteristics for sensing in harsh, caustic, high pressure, high temperature applications and fouling. Its features (benefits) include: • High Selectivity (able to detect specific chemicals) • Glass Free (higher reliability) • Bio-Fouling Resistance (longer life) • Large Range (enabling new apps) • Lower Limits of Detection (enabling [...]
United Science is commercializing a breakthrough platform innovation based on a technology invented by Professor Phillipe Buhlmann and licensed exclusively from the University of Minnesota. The platform technology can be leveraged to develop a series of products for selectively measuring the concentration of certain chemical species in complex solutions. This general class of sensor is called an Ion Selective Electrode (ISE). United Science is initially focused on satisfying an unmet market need for clean tech mining process sensors [...]
In our market research, we discovered that current solutions for analytical based carbon phases did not cover the gamut of separation products required to make carbon useful. For instance, a carbon HPLC column is more useful if there is a preparative or flash columns available based on the same separation platform. Our product line covers the entire range of analytical needs from SPE to Preparative.
United Science is to test market its recently introduced carbon on silica to select end users for evaluation and feedback on its performance compared to carbon sorbents currently in use.
