Experimental Determination of Residence Time Functions

The distribution functions, E t) and F t), can easily and efficiently be determined by tracer experiments. In this section, we will discuss the ways in which distribution functions can be obtained from primary experimental data. Let us assume that a continuously operating analytical instrument is available. The instrument should be installed at the outlet of
