HKL-4185 AAS for Determination of toxic copper substances in workplace air
Overview
HKL-4185 AAS for Determination of toxic copper substances in workplace air conforms to the ASTM D4185 Standard Practice for Measurement of Metals in Workplace Atmospheres by Flame Atomic Absorption Spectrophotometry Copper. Workplace air samples are collected on membrane filters and treated with nitric acid to destroy the organic matrix and to dissolve the metals present. The analysis is subsequently made by flame atomic absorption spectrophotometry (AAS).
Samples and standards are aspirated into an appropriate AAS flame. A hollow cathode or electrodeless discharge lamp for the metal being determined provides a source of characteristic radiation energy for that particular metal. The absorption of this characteristic energy by the atoms of interest in the flame is related to the concentration of the metal in the aspirated sample.
