An Overview- Advances in Chromatographic Techniques in Phytochemistry [PDF]
E3S Web of Conferences, 2023 The basic idea of the Chromatographic process is that the distinct compounds have different properties like solubility, adsorption, ion exchange, and affinity that can be regulated through various separation mechanisms causing the analytes to travel ...

Amphiphilic diblock copolymers as functional surfaces for protein chromatography [PDF]
, 2022 Stationary phase plays a crucial role in the operation of a protein chromatography column. Conventional resins composed of acrylic polymers and their derivatives contribute to heterogeneity of the packing of stationary phase inside these columns. Alternative polymer combinations through customized surface functionalization schemes which consist of ...

Singular Shocks in a Chromatography Model [PDF]
Journal of Mathematical Analysis and Applications, volume 439,
issue 2, year 2016, pages 766-797, 2015 We consider a system of two equations that can be used to describe nonlinear chromatography and produce a coherent explanation and description of the unbounded solutions (singular shocks) that appear in M. Mazzotti's model. We use the methods of Geometric Singular Perturbation Theory, to show existence of a viscous solution to Dafermos-DiPerna ...
