Waters ACQUITY Premier Protein SEC Column, 250A, 1.7 um, 4.6 x 300 mm, 1/pk - 186009964

Waters™ ACQUITY Premier Protein SEC Column, 250Å, 1.7 µm, 4.6 x 300 mm, 1/pk

Product Number: 186009964

Specifications

ACQUITY Premier Protein SEC 250Å, 1.7 µm Columns help scientists obtain reliable protein size variant separations (10,000 to approx 650,000 Daltons) via the synergistic coupling of Waters MaxPeak Premier High Performance Surfaces and novel BEH-PEO Particle technologies. These advancements in SEC column hardware and SEC particle technology work to minimize non-desired secondary ionic or hydrophobic interactions between proteins and the column to minimize costly method development work by allowing chromatographers to use a “generic” or “platform-type” method for many samples. Note:  The same column is also available with the Waters mAb Size Variant Standard at no additional cost. (p/n: 176005070)   Also note that for optimal SEC separation performance, this column is designed for use in UPLC SEC applications with an appropriate low LC system volume.

SEC Columns

Size-based separations of peptides, proteins, and viral vectors

Get unmatched batch-to-batch reproducibility with the wide range of Waters Size-Exclusion Chromatography (SEC) Columns and standards for protein and peptide characterization.

SEC is a powerful technique for aggregate and fragment analysis in the research, development, and manufacturing of biotherapeutic proteins, such as insulin and monoclonal antibodies (mAb).?With SEC, also known as gel filtration, you can separate proteins based on their size (hydrodynamic radii versus absolute molecular weight) in solution, with larger sized species eluting before smaller proteins. 

The?pore size?and?volume of the SEC particles?used in the packed column drives this isocratic based technique, so the column you choose matters.?As the molecular weight of the proteins of interest increases, SEC columns with comparatively larger pore size particles are selected.

ACQUITY UPLC columns

ACQUITY UPLC columns are the most technologically advanced LC columns ever created and are the only columns designed, tested and certified to withstand the pressures of UPLC Technology. Based upon the highly efficient 1.7 µm Bridged Ethyl Hybrid (BEH) particles and 1.8 µm High Strength Silica (HSS) particles, these columns are the first and only columns that allow separation scientists to achieve maximum speed, sensitivity and resolution without compromise. The particles and chemistries of the ACQUITY UPLC column family were carefully chosen to produce the ideal combination of ultra-performance efficiencies, wide pH range and complementary selectivities. ACQUITY UPLC BEH columns and ACQUITY UPLC HSS columns are the only columns recommended for use with ACQUITY UPLC Systems.

There is more to creating a UPLC particle than synthesizing a small particle. Many HPLC particles do not possess the mechanical stability and structural integrity to withstand UPLC operating pressures (e.g., 15000 psi/1000 bar). Why is pressure tolerance important? In order to realize the efficiency gains of sub-2 μm particles, the ability to routinely operate at higher linear velocities (e.g., higher flow rates) is required. These higher linear velocities combined with small, sub-2 μm particles result in higher operating backpressures. Waters has created two highly efficient, pressure-tolerant UPLC particles: the 1.7 μm Ethylene Bridged Hybrid (BEH) particle and the 1.8 μm High Strength Silica (HSS) particle.

The first ACQUITY UPLC particle created was the 1.7 μm Ethylene Bridged Hybrid (BEH) particle. This second generation hybrid particle is one of the key enablers behind UPLC technology and is available in five column chemistries: C18, C8, Shield RP18, Phenyl and HILIC. Because this is a hybrid particle, a wider usable pH range (up to pH 1-12) makes method development faster and easier. BEH particles are also available in HPLC particle sizes (2.5, 3.5, 5 and 10 μm) in the XBridge family of HPLC columns, thus allowing seamless transfer between HPLC and UPLC separations.
