Atomic Absorption Spectrophotometer (Z-8200/Z-9000, Hitachi Ltd.)
The instrument analyzes inorganic elements in the samples at the range of ppm (mg/l) and/or ppb (ug/l) levels. Elements in the samples are atomized in flame or graphitge atomizer, and each element absorbs characteristic wavelength-light discharged from cathode lamp. By measuring the absorbance of the light, quantitative analyses are carried out.
