This example shows the selectivity enhancement with frequency.  

Here is the calculation of the solution for ω =1.   

Now change the frequency to ω=0.5,  

Now change the frequency to ω=5, this takes a while to calculate and the maximum steps needs to be increased because of the higher fluctuation frequency.    

We should be sure that the frequency change does not affect the average mass transfer coefficient.
