Guiochon, G., Felinger, A., Shirazi, D. G., & Katti, A. M. (2006). Fundamentals of Preparative and Nonlinear Chromatography. Academic Press.
The definitive reference on chromatography theory. Covers equilibrium theory, mass transfer models, and nonlinear chromatography in depth. Dense but comprehensive.
Schmidt-Traub, H., Schulte, M., & Seidel-Morgenstern, A. (Eds.) (2020). Preparative Chromatography. Wiley-VCH, 3rd edition.
A practical reference that bridges theory and application. Covers process design, optimization, and scale-up with worked examples. Good balance between rigor and accessibility.
Carta, G., & Jungbauer, A. (2020). Protein Chromatography: Process Development and Scale-Up. Wiley-VCH, 2nd edition.
Focused on protein purification. Covers adsorption equilibria, mass transfer, column dynamics, and practical process development. Especially relevant for biopharmaceutical applications.
Bellot, J. C., & Condoret, J. S. (1991). Liquid Chromatography Modelling: A Review. Process Biochemistry, 26(6), 363–376.
A review article rather than a textbook, but a useful overview of the different modeling approaches and their assumptions. Good starting point for newcomers.
