WebThe ion exchange capacity is expressed as eq/L (equivalents per litre of resin). The unit of mole should be avoided altogether in ion exchange, as it does not take valence into account and brings only confusion. For reference: 1 eq = 1 mole / valence. The operating capacity is always smaller than the total capacity. WebSample can be loaded manually or using a sample pump.

Dividing the amount of crude by the found load factor ( 2.75 g / 15 % to 2.75 g/ 20 %) gives 13.8 to 18.3 g of sorbent needed. The best cartridge available would be the 25 g pre-packed one ( see chart below ). WebThe capacity can be calculated by using the relationships between dynamic binding capacity (DBC) and residence time. By leveraging the capacity, loading amount, and the required conditions, the optimum LFG can be designed. The method was verified by ion-exchange and protein A chromatography of monoclonal antibodies (mAbs). tld-inc
