HPLC Guard Columns and Cartridges
Waters Corp ACQUITY UPLC CSH Phenyl-Hexyl VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk
ACQUITY CSH Phenyl-Hexyl columns are used to provide alternative analyte selectivity and are a valuable tool for method development. The trifunctionally bonded C6 phenyl ligand is a robust, low bleed sorbents that selectively retains polyaromotic compounds through pi-pi interactions. The VanGuard pre-column connects directly to the inlet of the ACQUITY UPLC column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.

Sepax Technologies Inc Sepax HPLC Column HPLC GUARD Column, BioMix SEC-300, 3 µm, 4.6 x 50 mm
Utilizing proprietary surface technologies and 3 µm particle size, BioMix-300 phase is made of uniform, hydrophilic, and neutral nanometer thick films chemically bonded on the high purity and enhanced mechanical stability silica. The proprietary surface technologies allow the chemistry of thin film formation to be well controlled, which results in high column-to-column reproducibility. The nature of the chemical bonding and the uniformity of the thin film benefit BioMix-300 phase with high stability. BioMix-300 resin is produced from 3 µm spherical silica particles with a pore size of 300 Å. BioMix-300 columns are packed with a proprietary slurry technique to achieve uniform and stable packing bed density for maximum column efficiency. BioMix-300 phase is designed to ensure highest resolution and maximum recovery for a broad range of analytes such as bispecific mAb, hydrophobic samples etc.
Waters Corp ACQUITY UPLC Protein BEH C4 VanGuard Pre-column, 300Å, 1.7 µm, 2.1 mm X 5 mm, 10K - 500K, 3/pk
Waters Protein Separation Technology columns are QC tested and optimized to separate proteins based on size, hydrophobicity and isoelectric point. If you compare to traditional C18 phases, the C4 ligand is less retentive and will minimize protein carryover, increase protein recovery, and improve peak capacity. The VanGuard pre-column connects directly to the inlet of the ACQUITY UPLC column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
Sepax Technologies Inc Sepax HPLC Column GP-C4, Guard cartridge with holder, 5 µm, 120 Å, 2 x 10 mm
Monomeric and fully endcapped GP-C4 packing is bonded with butyl groups that lead to moderate hydrophobicity. GP-C4 columns have unique selectivity and peak symmetry with moderate retention for separations of acidic, neutral and basic organic compounds, such as pharmaceuticals, peptides, and organic acids.
