Waters Corporation VanGuard Pre-column, C4, 300Å, 1.7 μm, 2.1 mm X 5 mm
- QC tested and optimized for protein separation based on size, hydrophobicity, and isoelectric point.
- C4 ligand minimizes protein carryover, increases recovery, and improves peak capacity.
- Direct connection to column inlet minimizes extra column volumes and reduces leaking.
- Protects analytical columns from contaminants, prolonging lifetime.
- Enhances analytical performance by filtering chemical and particulate impurities.
- Tolerates pressures up to 18,000 psi (1,240 bar) in UPLC system applications.
- Utilizes BEH Technology C4, 300Å pore, and 1.7μm particles.
- Batch QC tested with peptide map for consistent performance and increased column life.
- Employs same packing material as analytical columns for consistent reversed-phase LC performance.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 3 µm, 300 Å, 2 x 10 mm
Wide range of pore sizes and high compatibility with 100% aqueous phases make Bio-C18 columns ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. The specially designed surface bonding chemistry and the pore sizes allow for extended retention and selectivity for polar and hydrophilic compounds, such as peptides and amino acids. C18 monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
Advanced Materials Technology HALO 1000 Å Diphenyl, 2.7 µm, 2.1 x 5 mm, Guard Column 3pk
HALO BIOCLASS Diphenyl 1000 Å Protein columns made with innovative large pore Fused-Core particle technology provide best in class performance for high resolution separations and better recoveries of large biomolecules such as mAbs, versus smaller pore size columns. HALO 1000 Å columns are optimized for high performance in HPLC, UHPLC, and LCMS large molecule applications delivering excellent reproducibility and column lifetimes.
