Dynamic selectivity profile

Cu/Cd dynamic selectivity profiles in the strip phase, obtained experimentally and calculated using model equations, are presented in Fig. 6.10. The calculated maximum selectivity of The Cu/Cd separation factor... 

Several simulation runs follow for the two cases. The runs are represented by their initial conditions and a few selected profiles in order to show the progress of the dynamics. The spatial domain was divided into 100 segments so that A.x = 1 x 10. The dimensionless time increment for these runs was At = 1 x 10. At each time interval, the linearized response converged within 5 iterations to the nonlinear response. Figure 8.23 shows the dynamics of a startup from a cold reactor with a single steady state. For this run, the system exhibits uniform asymptotic stability. 

The electrolytic conductivity detector is a good alternative to the FPD for selective sulfur detection. The ELCD has a larger linear dynamic range and a linear response to concentration profile. The ELCD in most cases appears, under ideal conditions, to yield slightly lower detection limits for sulfur (about 1-2 pg S/sec), but with much less interference from hydrocar-... 

The field of curve resolution was bom in response to the need for a tool to analyze multivariate experimental data from multicomponent dynamic systems. The common goal of all curve-resolution methods is to mathematically decompose the global instrumental response into the pure-component profiles of each of the components in the system. The use of these methods has become a valuable aid for resolving complex systems, especially when obtaining selective signals for individual species is not experimentally possible, too complex, or too time consuming.
