ELECTRONIC AAS SYSTEM, FIRE ASSAY
DAAS-F6 electronic AAS system ( or fire assay) is a single beam atomic absorption spectrometer, which is controlled and data processed by external computer and internal CPU chips. The DAAS-F6 can be used to measure the concentration of macro, micro and trace metal elements and half-metal elements in various kinds of substances.
Atomic absorption spectrometry is a technique exploiting the fact that atoms at ground state may absorb the radiation of characteristics wavelength. As is known the atoms are usually at ground state. For each element, the amount of energy required for an atom to transit from ground state to excited state is specific, and in general it is called characteristic wavelength. The atomic absorption spectrometry typically makes use of hollow cathode lamp as the light source to emit the characteristic wavelength of a particular element. When the light passes through the atomic vapor, it is absorbed by the vapor. The concentration of the element can then be determined through the calculation of the absorption rate.
DAAS-F6 provides with three reading methods Continuum, Retention and Peak Height for measuring absorbency, density and emission intensity.
APPLICATIONS:
- Metallurgy, steel and non-ferrous metals.
