摘要： In atomic absorption spectrophotometers such as Zeeman atomic absorption spectrophotometer, the present invention is characterized in that the correction timing of background absorption in sample light is made to coincide with that of reference light so as to improve the accuracy of the output signals of the spectrophotometer. To accomplish this object, the present invention constitutes a calculation processing unit for storing and calculating signals by means for separating one signal consisting of sample signals and reference signals applied thereto from amplification means for amplifiying photoelectrically converted signals into sample and reference signals, and storing them, means for calculating respectively the mean values of two time adjacent signals of one of the sample and reference signals to prepare a signal of the mean values, and means for calculating the difference of the logarithmic converted values of the signals of the other of the sample and reference signals and those of the signals of the signal of the mean values at the same points of time, and obtaining correction signals of background absorption.

摘要： A double polarized light beam spectrophotometer of a light-source modulation type. A modulated light beam emitted by a light source is conducted through specimen atom vapor generated by a graphite atomizer. Wavelength of light undergone atom absorption is selected and spatially separated into a pair of linearly polarized light beams perpendicular to each other. The pair of the linearly polarized light beams separated are alternately passed through a chopper and received by a photoelectric conversion device to be converted into electric signals which are utilized for determining atomic absorption of the specimen. The phase of modulation of light radiated from the light source is synchronized with phase of a current supplied to the graphite atomizer for heating thereof and the switching timing of the chopper.

摘要： A spectral source comprises a lamp containing an anode and a cathode in an inert gas. The anode and cathode are different in shape and connected to a high-frequency power source to produce a high-frequency discharge between the anode and cathode to cause both sputtering of the cathode and excitation of a radiation having the spectrum according to the material sputtered from the cathode. The application of solely high-frequency power prevents adherence of the sputtered material to the interior walls of the lamp bulb thereby allowing a reduction of the dimensions of the lamp bulb, prolongating the life time of the lamp and increasing the stability and intensity of the radiation. A magnetic field may be applied to the radiation for Zeeman modulation. Due to the relatively small dimensions of the lamp bulb, relatively small and inexpensive magnets may be used.

摘要： An absorption profile indicative of a relation in atomic absorption spectroscopy between the absorbance of a desired element and time has a constant half-width independent of the concentration of the desired element in a sample, and hence the half-width of absorption profile with respect to the desired element can be previously determined from data which is obtained by the measurement of a standard sample. In an atomic absorption spectrophotometer herein disclosed, the half-width of absorption profile is previously determined in the above-mentioned manner, and the true peak value of an absorption profile obtained by measuring a sample which contains the desired element at a high concentration, is calculated using the time width of this absorption profile at a predetermined absorbance and the previously-determined half-width.

摘要： A spectrophotometric analyzer disclosed by this invention has two monochromators capable of operating independently of each other. In each monochromator, a light beam from a light source is made to be incident on an entrance slit, and, after dispersed and wavelength scanned, issued from an exit slit as an analyzed light beam. These analyzed light beams are detected by detectors. The entrance slits and the exit slits of the two monochromators are disposed rotation symmetrically. This can simplify the operation of switching between a series mode where the analyzed light from the exit slit of the one monochromator is made to be incident on the entrance slit of the other monochromator and a parallel mode where the both monochromators operate for detection independently from each other.
