Latest Patents

Viviane holds a patent for a method to measure surfactants in fluid. This invention is directed towards methods and compositions for identifying the presence of surfactants in water. The invention is superior to prior art as it can form a colorful complex in half the time, avoids difficult separation steps, utilizes a safer solvent, and prevents the formation of messy foam. The process involves adding a cobalt thiocyanate reagent to the water, which forms a colorful complex with the surfactant. Chloroform is then added, allowing the cobalt reagent to facilitate the migration of the surfactant into the chloroform, where it can be easily identified using a UV-vis spectrometer.
