This video gives an overview of the simplest implementation of a automated calibration system. This system can be configured to address many plug and play fluidic and sensor systems.
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 residual unreacted xanthate in froth solutions.
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, [...]
