Two Macromolecular Separation Systems with multiple Detectors

System 1”) and Size-exclusion chromatography (SEC) instrument coupled to MALS (infrared laser)/UV/RI/FL (“System 2”). There is a need to move and use detectors between the Systems. System 1 shall contain both AF4 and SEC separation capabilities and MALS (equipped with red laser), DLS, PDA, RI, and V

ISC detectors. The AF4/SEC instrument shall also contain a fraction collector. The System must include quaternary HPLC pump, autosampler, AF4 flow-control module, two analytical AF4 channels (which can be used with aqueous buffers and organ
