Waters Corporation introduced the Waters ACQUITY Arc Bio System, a versatile, iron-free, bio-inert, quaternary liquid chromatograph specifically engineered to enable the efficient transfer and improvement of bioseparation analytical methods regardless of the LC platform on which the original method was developed. The ACQUITY Arc Bio System is ideally suited to run reversed-phase, ion exchange, size exclusion and hydrophobic interaction LC methods with minimal carryover and maximum recovery of biomolecules. The ACQUITY Arc Bio System’s flow paths are made of non-stainless steel and iron-free bio-inert materials designed to minimize undesirable protein interactions and maximize system robustness under salt and pH extremes. What also sets the instrument apart is the unique Arc Multi-flow path™ technology which delivers plug-and-play compatibility with HPLC or UHPLC methods through a selectable dwell volume, emulating the dwell volume of the original instrument. This minimizes the time it takes laboratories to redevelop methods from internal and external partners.
