Increasing complexity of modern biotherapeutic characterization, monitoring, and quality control assays
require even more demanding analytical techniques to accurately define and assess critical quality
control attributes (CQAs) related to product safety, stability, and efficacy.
The ACQUITY™ UPLC™ H-Class PLUS Bio System provides the same high resolution, high sensitivity
separations you have come to expect from UPLC Technology, with the flexibility and ruggedness
to run all the chromatography modes you require – ion exchange (IEX), size exclusion (SEC),
hydrophilic interaction (HILIC), hydrophobic interaction (HIC), or reversed-phase – all on one system.

fraction collection from your high efficiency
UPLC separations to enable additional
targeted studies.
Versatile column management
Support for analytical LC column
dimensions up to 300 mm with
capacity to automatically select
between as many as six analytical
columns. Equipped with independently
controlled temperature zones, active
pre-heating, and eCord™ Intelligent
Chip Technology for Waters™ columns.
Bio-inert flow-through-
needle injector
Volume range of 0.1 to 1000 µL
and ultra-low sample carryover
performance compatible with your most
sensitive LC and LC-MS applications.
Auto•Blend Plus technology
Program gradients directly in terms of pH,
molarity, or organic composition to minimize
manual mobile phase preparation, reduce
human error, and accelerate method robustness
testing for chromatographic methods.
bioQuaternary or bioBinary
solvent management
Precise and accurate blending of up to
four solvents with automated solvent
compressibility compensation available
with the bioQuaternary solvent manager.
Increase method development flexibility with
an optional, integrated solvent select valve,
providing access to six additional solvents.
Deliver precise and accurate binary solvent
blending with the bioBinary solvent manager
at pressures up to 15,000 psi.
Flexible sample support
Accepts either vials or ANSI well plate
formats. Extend capacity for high
throughput and open access environments
with the optional Sample Organizer.
Gradient SmartStart
Easily adjust for system volume
differences when transferring methods
from an alternative LC system without
alteration to the method table.
HIGHEST RESOLUTION OF ANY BIO-INERT QUATERNARY OR BINARY LC SYSTEM
A BETTER PERSPECTIVE FOR YOUR BIOSEPARATIONS
Leverage the benefits of UPLC Technology to improve your HPLC methods. By scaling your bioseparations methods
to UPLC, your assays will benefit from the combination of increased speed, resolution, and sensitivity that comes with
modern small particle chemistries.
Purpose built for biopharmaceutical
characterization, the ACQUITY UPLC
H-Class PLUS Bio System leverages high
resolution column technology, advanced
detection, and intelligent informatics to
increase the information you receive from
each and every sample.
With exceptional quaternary or binary gradient
precision and accuracy formation, reliable and
robust separations can be achieved for your
most challenging bioseparations, day-after-
day and year-after-year.
UPLC and ACQUITY UPLC BEH Peptide Columns deliver unparalleled resolution and
reproducibility in peptide mapping, here of infliximab (five overlayed chromatograms).

Hydrophobic interaction chromatography separation of six proteins (HIC Protein Standard) by the Protein-Pak™ Hi Res
HIC 2.5 µm, 4.6 x 100 mm Column. Mobile phase A: 2M (NH4)2SO4 in 50 mM Na2HPO4 at pH 6.9; Mobile phase B:
50 mM Na2HPO4/Na2HPO4 at pH 6.9; Flow rate: 0.6 mL/min; Gradient: 0–100% B in 15 minutes.
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.
