The present application describes various improvements and further developments to the Expanded Bed Adsorption (EBA) technology. In particular, the application describes an EBA process where elution is performed in fluidized mode, i.e., in expanded bed mode, the so-called All Expanded Process. This improvement which is based on the use of controlled density particles, e.g., particles having a density of at least 1.3 g/ml, provides valuable advantages with respect to use of reduced amounts of elution buffer.
