Abstract
The present disclosure is directed to liquid chromatography columns and methods utilizing a stationary phase sorbent having two or more gradient factors. Each of the two or more gradient factors varies in a progressive manner along a length of the stationary phase sorbent in a direction from an inlet to an outlet of the column (i.e., along a length of the column). As a result of including these new continuous stationary phase gradients, new selectivities allowing for separation and analysis of complex samples including large biomolecules is achievable.
