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...
A procedure is described for the optimization of a previously
described continuous analysis adaptation of the Pearl-Benson or
nitroso method for estimation of spent sulfite liquor (SSL) or ligno-sulfonates.
The optimized procedure has a response time of 6.5 minutes. In order to monitor samples whose SSL concentration is
between 0...
