    摘要: A Zeeman atomic absorption spectrophotometer which monitors atomic absorption signals after a sample is introduced into the chemical flame atomizing portion. A signal peak value is measured in the portion of atomic absorption signals rising after the sample is introduced, or in the portion of atomic absorption signals breaking after the introduction of the sample is discontinued. A relation between the peak value and the sample concentration establishes a monovalent function. According to the conventional method, a relation between an average value of atomic absorption signals within a predetermined period of time and the concentration of specimen establishes a divalent function, and it is difficult to measure the samples, particularly in high-concentration regions. According to the present invention, however, it is possible to measure the samples of even high concentrations without having to dilute the samples.

    摘要: A magneto-optic spectrophotometer for detection or identification of atoms or molecules contained in the sample by utilizing phenomena of birefringence or rotation of polarization caused by the atoms or the molecules in a magnetic field is constructed as follows. Linearly polarized lights are incident on a space where atoms or molecules to be detected exist in a magnetic field. The lights having passed through said space are separated into two beams of lights of polarization components perpendicular and parallel to the polarization of the incident lights. The perpendicular components are used as the signal lights, and the parallel components the reference lights. The signal lights and the reference lights are spectrally analyzed by a wavelength selector in which a signal light and a reference light of a wavelength to be selected are incident on an identical dispersive element. The signal lights and the reference lights are detected by respective detectors. Then, the ratios of the outputs of the signal light detectors to the outputs of the reference light detectors are obtained. By this construction the intensities of the scattered lights by atoms or molecules to be detected can precisely be measured.

    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.

    摘要: In measuring a change in the polarization state of light attributed to magnetooptic anisotropy, a means for generating optic anisotropy is added to a light source or onto an optical path extending from the light source to a polarization analyzer. This allows high precision analysis of the polarization state of light emergent from the polarization analyzer.
