Two movable photo-multiplier tubes are set in the position of the plate holder of a medium quartz spectrograph. The photo-current of each is amplified by an AC amplifier, and, after rectification, is used to charge a condenser. A thyratron is connected parallel to the condenser for the internal standard line (Al 2660A). At a present value of the voltage of this condenser, the thyratron operates so as to switch off the reading instrument which is connected with the other condenser for the analysis line...

Two movable photo-multiplier tubes are set in the position of the plate holder of a medium quartz spectrograph. The photo-current of each is amplified by an AC amplifier, and, after rectification, is used to charge a condenser. A thyratron is connected parallel to the condenser for the internal standard line (Al 2660A). At a present value of the voltage of this condenser, the thyratron operates so as to switch off the reading instrument which is connected with the other condenser for the analysis line (Cu 2247 A). The final reading on the meter is proved to be proportional to the ratio of intensities of the two spectral lines.

The design feature of a direct-reading spectro-analyser with emphasis on the electronic circuit design is presented in this paper. This instrument is stable, speedy, and accurate. The first and second order spectral ranges are respectively 2000-6000 and 2000-3000 A. The mechanical construction of the optical system is so characterized that two (for first order) or four (for second order) pickups can be set exactly on the same spectral line. A line-frequency, high-voltage and high-energy spark source system is employed with adequate sensitivity. The measuring system consists of a pulse amplifier, a rectifier, an integrator, and a pulse counter. The operation of this instrument is completely automatic after the mounting of the sample. Finally, typical operational data are illustrated.
