The aim of this work was to investigate an accurate, fast, and stable numerical scheme for solving chromatographic model equations, especially, but not limited to, those in the presence of a shock front. Existing solution techniques, such as finite-difference and finite-element methods, are briefly reviewed and compared with the finite-volume method, which so far has been applied to only a limited extent to the solution of model equations in the chromatographic community. One well-established, accurate, and stable finite-volume technique includes the application of appropriate flux limiters. Investigation of the elution profiles of linear and nonlinear chromatographic conditions were carried out over a wide range of flux limiters in terms of accuracy, stability, and computational time. Based on the simulation results, the van Leer flux limiter in the realm of finite-volume methods was found to be the most suitable in terms of accuracy and computational time for solving chromatographic model equations.
