Abstract

956, 836. Photo-electric absorption analysis apparatus. KABUSHIKI KAISHA HITACHI SEISAKUSHO. Nov. 8, 1962 [Nov. 9, 1961], No. 42258/62. Heading G1A. Absorption analysis apparatus comprises a light source S1 emitting suitable spectral lines, which need not be narrow, a flame into which the' test sample is introducted, S2, a monochromator M of low dispersion and low resolving power followed by a interference spectrometer I of high dispersion and resolving power. The sample may be vaporized in the flame and the absorbance at the wave-length of a resonance line of the element of interest determined and compared with the absorbance of known concentrations of the element similarly introduced to determine the amount present in the sample. The apparatus makes it possible to measure accurately peak intensities at any required wavelength. The interference spectrometer may perform a wavelength scan and incorporate a photosensitive device D whose output after amplification is fed to a recorder R.
