Chemical Stability of CIMac™ Analytical Columns

The stability of QA, DEAE and SO3 CIMac™ Analytical Columns was tested according to the CIP (Cleaning In Place) procedures described in the respective Product Specification Sheets (see Table 1). We compared the separation of a mixture of test proteins, the dynamic binding capacity for BSA and the pressure drop after 50 and 100 CIP procedures with the initial characteristics of the columns.
