Agilent PL aquagel-OH SEC Columns
for Biomolecule Analysis
size exclusion Chromatography (seC)
Biomolecule SEC with durability and versatility
Aqueous size exclusion chromatography (SEC) is widely used for the determination of molecular
weight distributions of naturally occurring water soluble polymers, such as macromolecular
biomolecules. This includes natural products and derivatives which may be used as excipients
and active ingredients in pharma applications.
The PL aquagel-OH series provides a chemically and physically stable matrix for reliable aqueous
SEC separations. The columns are packed with macroporous copolymer beads with an extremely
hydrophilic polyhydroxyl functionality. The “neutral” surface and the capability to operate across a
wide range of eluent conditions provide for high performance analyses of compounds with neutral,
ionic and hydrophobic moieties, alone or in combination. PL aquagel-OH is available for analytical
and preparative applications.
The excellent stability of the PL aquagel-OH packing material allows the eluent to be tailored to suit
the polymer, while retaining the high column efficiency. For ionic interactions, the eluent can be
modified by the addition of salt and/or the adjustment of pH. For water soluble polymers with a
hydrophobic character, only the addition of a weak organic solvent (methanol) is required to inhibit
hydrophobic interactions.
PL aquagel-OH analytical columns
Available with mixed and individual pore sizes, and 5, 8 and 15 µm particle sizes, to cover a very
wide range of molecular weights.
PL aquagel-OH preparative columns
For rapid and convenient scale-up from analytical separations. The columns are packed with the
same robust macroporous particles as the analytical column range.
