Applicability of the critical chromatography concept to proteomic problems. II. Effect of mobile phase on the separation of peptides and proteins taking into account the amino acid sequence.
The effect of parameters of a binary mobile phase (chemical properties of components, gradient profile, flow rate, and pH) on the separation of peptides and proteins is theoretically investigated using a model of critical chromatography (model BioLCCC). It is demonstrated that the retention volume of peptides can be inverted by changing separation conditions.
