Atomic absorption / emission spectrometer

Description of the instrument

Atomic absorption and emission spectroscopies are techniques used to determine the concentration of a specific metallic element in a sample. These two techniques require that the samples, in liquid form (diluted in acid solution), be aspirated, then, in the form of an aerosol, are mixed with combustible gases (acetylene and air). The mixture is then injected into a flame whose temperature varies between 2100C and 2800C. During combustion, the atoms contained in the sample are reduced to their ground state (not excited) by absorbing or emitting light at wavelengths characteristic of each element.
