Morris Slavin looks at 'rainbows', which are actually detailed analyses of various chemical substances

Morris Slavin, in charge of the spectroscopic laboratory of the chemistry department, Brookhaven National Laboratory, Upton, NY, looks at 'rainbows', which are actually detailed analyses of various chemical substances. The analysis begins with vaporization of a substance in an electric arc, to produce an incandescent gas.  The light given off by the gas is separated into its different components by an instrument called a spectrograph (not shown), much as a cloud scatters sunlight into the spectrum of visible colors in the rainbow.  Each of the 98 elements in the periodic table can be made to register its own characteristic spectral pattern on a photographic plate.  The binocular microscope (foreground) is used to examine the photographic plate in what has become a standard method of analysis in many laboratories., Credit Line: Photo courtesy Brookhaven National Laboratory.
