20090288962 | Electrochemical Sensor and Methods for Making and Using Same - A mercury-free, electrochemical sensor is described that includes a self-assembled monolayer on a mesoporous support (SAMMS) composite and a fluoropolymer component that is deposited on a measurement surface. The SAMMS component provides outstanding metal preconcentration. The fluoropolymer component acts as an antifouling binder. The sensor can detect various metals at a low detection level in the presence of fouling agents and without sample pretreatment. The sensor is also able to detect mixtures of metals simultaneously with excellent single and inter-electrode reproducibility. Service lifetimes are excellent. | 11-26-2009 |
20100077837 | Porous Thin Film and Process for Analyte Preconcentration and Determination - A porous thin film and a method are disclosed. The film has a generally uniform thickness and includes fused silica particles that provide multiple types of pores in the film. Particles are generally uniformly distributed on a surface and have a generally open structure that provides the film with an open interface readily accessible to fluids. The film provides for preconcentration of, e.g., heavy metals in fluid and gas samples that provides for direct determination of the analytes. | 04-01-2010 |
