Batch chromatography with Langmuir isotherms under ideal conditions

This tool calculates the outlet history (chromatogram) in a batch column using an explicit analytical solution for the governing equations:

\[ \frac{\partial}{\partial t} \left( c_j+ \frac{1-\epsilon}{\epsilon} \frac{q_{s,j}b_jc_j}{1+b_1c_1+b_2c_2} \right) + u^L\frac{\partial c_j}{\partial z} = 0 \quad \left(j=1,2\right)\]

The results are valid for binary separation with competitive Langmuir isotherm under ideal conditions when the adsorbent is initially fully regenerated.
