Determination of the Uncertainty of the Flame Atomic Absorption Spectrometer for Copper, Cobalt, Cadmium, and Nickel

摘要

The sources of uncertainty in the determination of copper, cobalt, cadmium, and nickel, originating from the flame atomic absorption spectrometer, were studied. They were identified and divided in three main groups according to their origin—from the flame, from the light source (hollow-cathode lamp), and from the optics. The combined uncertainty of the flame atomic absorption determination was experimentally determined.
