United Science Presents at SME

United Science presented its recent work on custom built xanthate sensor for the flotation industry.  The work was supported in part by the National Science Foundation, FLSmidth, and Freeport McMoran.   Key findings from the study showed that the sensors could measure...

PFOA and PFOS Sensors

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...

Sensor for PFOA Under Development

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...

Xanthate Ion Selective Electrodes

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...
