abstract = {ChromaTech is a simulator for preparative liquid
chromatography processes with mass transport described by
the pore and surface diffusion general rate model. A
discontinuous Galerkin spectral element method is used for
spatial discretization with exponential decay of
approximation errors within elements. The code is validated
by numerically reproducing a high-precision reference
obtained with CADET-semi-analytic. The performance of
ChromaTech is tested by comparing against CADET, a dedicated
code based on a weighted essentially non-oscillatory finite
volume method with second (low) order spatial accuracy.
Reassuringly, ChromaTech provides exactly the same
chromatograms as CADET for multicomponent protein
purification cases with linear and non-linear adsorption
dynamics. However, the numerical results show, that
ChromaTech has superior efficiency in terms of computational
cost and discrete problem size without compromising
stability. The spatial discretization is the major
difference between the two codes for solution of the pore
and surface diffusion general rate model. Thus, it
demonstrates, that spectral methods are not just competitive
with second (low) order accurate methods often used by
default, but simply a superior approach for spatial
discretization of liquid chromatography flow problems in
terms of computational efficiency.},
