Abstract
  • An automatic, continuous analyzer has been developed which is suitable for estimating the level of spent sulfite liquors (SSL) in laboratory samples. The analyzer makes use of a version of the Pearl-Benson, or nitroso method, and, in its present form, is useful for samples whose actual SSL solids concentrations are in the range 0-100 ppm. A number of detailed investigations related to the development of the analyzer, but also related to various aspects of continuously flowing analytical streams in general, are discussed. These investigations include consideration of the mechanism by which the pump activates the flowing system and the effects upon flow characteristics which accompany system modification. A rudimentary electrical analog for the pump and its system has been proposed which qualitatively explains the observed behavior of the real system. The response characteristics of an unbroken flowing stream are considered and compared with those expected upon the basis of laminar flow.
