Separation mode map
Choose the interaction that should drive retention
These groups describe the dominant practical mechanism. Real retention can combine partitioning, adsorption, charge, size, and stereochemical interactions.
Mode versus format: UHPLC, preparative LC, capillary LC, and nano-LC describe pressure or scale and flow formats; each can use several of the separation modes shown here.
