KWRRI Research Reports


Construction and testing of a double-beam absorption spectrographic analysis system using a d. c. arc multielement source has been conducted. An optical system design which brings analytical and reference beams together to illuminate the upper and lower portions of the spectrograph slit has been shown to be functional. However, ad. c. arc will not serve as a multielement source for the intended purposes because of excessive thermal broadening of emission lines.

A direct excitation d. c. arc method was reviewed which can be used for the rapid determination of some cations in water.
