Copper and Silver Analysis and Testing

Copper-silver ionization is a disinfection method applied primarily to hot water distribution systems for the control of Legionella.

Principle

Water samples are analyzed for elemental copper and or silver by flame atomic absorption. A sample is introduced as an aerosol into the flame (energy provided by air-acetylene) through which a light beam passes (at a wavelength specified for the element of interest) and where the light is absorbed. The amount of light absorbed is proportional to the amount of analyte in the water. This nebulizer utilizes a ceramic, one-piece, impact bead structure which improves nebulization (nebulize – to reduce to a fine spray) efficiency.
