Latest Patents

John W Foerster holds a patent for a method titled "Situ copper (I) - A method for determining copper (I) concentrations in water or seawater samples." This method involves dipping a probe into the sample for a sufficient time to produce a color change. The probe is then removed and compared to a color standard to determine the concentration of copper (I). The probe includes a substrate and an impregnate, bathocuproine, which complexes to copper (I) to produce a colored complex that is less toxic to marine organisms than copper (I). The substrate is an ionomeric polymer with hydrophobic chains and hydrophilic cation exchange sites, with a preferred embodiment being a sulfonated perfluoropolymer.
