Atomic absorption spectrophotometer |
摘要 |
There is provided an atomic absorption spectrophotometer wherein a magnetic field having a suitable value is applied to a light source radiating the emission spectral light of the atom to be analyzed in the advance direction of the radiated light in order to cause the Zeeman effect so that the wavenumber of a component which is included in the spectra shifted in wavenumber and which is varied to have a smaller wavenumber may coincide with or approach the wavenumber whereat the absorption spectrum is maximized, thereby the sensitivity of the atomic absorption being raised, the linear region of the working curve being improved, and the emission spectral light being stabilized.
