HPLC Guard Columns and Cartridges
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 HSS PFP VanGuard Pre-column, 100Å, 1.8 µm, 2.1 mm X 5 mm, 3/pk
ACQUITY UPLC HSS PFP is a non-endcapped silica-based column designed for low pH separations that require alternative selectivity compared to a fully endcapped, high coverage C18 phase. ACQUITY HSS PFP columns are fully scalable and transferable to HPLC separations.
Thermo Scientific GUARD COLUMN C18 MG 2/PKG. 3
Drop-in guard cartridges, MG, C18, 4x10mm, 2/pk - fits guard column holder Cat No. NC0527629 (No. 88-12415)
Waters Corp DeltaPak C18 Sentry Guard Cartridge, 300Å, 5 µm, 3.9 mm X 20 mm, 1K - 30K, 2/pk
Delta-Pak packings, ideal for the separation of peptides, proteins, and natural products, are based on a highly stable, bonded, endcapped 5µm or 15µm spherical silica. Delta-Pak is available in two different pore sizes (100Å and 300Å) with either C4 or C18 bonded phase. Delta-Pak packings are available in different cartridge and column configurations, providing consistent and predictable scale-up capabilities for milligram-to-gram scale purification. Also, by having the same chemistry available on a high-efficiency 5µm particle, you can easily check the purity of your fractions.
