Automated determination of relative turbidity with a fluorometer

In ecological studies on particulate materials in aquatic environments it is often useful to have a method available which can give a rapid indication of the in situ occurrence of maxima in particle concentrations. For this purpose we have employed a G. K. Turner fluorometer as described by Stephens (Deep-Sea Res., 14 465, 1967). The advantages of this instrument are that it is easily maintained, it is readily adapted to automation, and it is complete without an outboard sensing device. [Pg.259]
