RELIABLE OPERATION UNDER DEMANDING CONDITIONS
Assays utilizing IEX, SEC, and HIC modes of chromatography typically utilize high ionic strength mobile phases
containing denaturing agents. The ACQUITY UPLC H-Class PLUS Bio System’s bio-inert flow path is made of
non-stainless steel and iron-free materials to minimize undesirable protein interactions and maximize system
robustness. The result: a system that is ideally suited for routine, trouble-free operation with maximum recovery
of biomolecules and consistently high system performance.
ON-DEMAND MOBILE PHASE CREATION
The bioQuaternary Solvent Manager (bioQSM) automatically blends mobile phase combinations and
gradients on demand, enabling you to obtain the optimum retention and selectivity requirements for
your analysis. Designed with bio-inert materials, the bioQSM accommodates the aqueous,
high ionic strength mobile phases and organic solvents used in biopharmaceutical applications.
Auto•Blend Plus technology automatically blends your mobile phase to a specified pH and ionic
strength or organic modifier percentage, for an infinite set of analytical conditions. By blending
online to the desired pH and ionic strength conditions, you can significantly reduce the number
of buffers you need to prepare for method development and routine everyday use.
