NEW CAPABILITIES OF SPECTRAL ANALYSIS OF METALS AND ALLOYS WITH THE USE OF PRELIMINARY BATCHING BY CONTACT SPARK DISCHARGE,
Abstract
Photoelectric recording of the spectrum of small batching of substance has an advantage over photographic recording not only in the part of a significant shortening of the time of measurement of the spectral lines but in relationship to a significant increase in sensitivity. Thus, for example when working with samples containing sulphur for development on the spectrograph ISP-22 with glass optics of the sulphur line 5320.6 A it was necessary that each spectrum be obtained from six support electrodes with the products of transfer - 6-fold exposure was carried out for each spectrum; on the vacuum polychrometer one electrode was sufficient for the measurement of sulphur line intensity. Thus, small doses produced by contact-spark transfer a substance may be successfully measured during photoelectric recording of the spectrum on an ordinary apparatus both for analytic purposes and when solving problems of a research nature.
