HPLC Guard Columns and Cartridges
Waters Corp BioSuite Diol (OH) Guard Column, 4 µm, 4.6 mm X 35 mm, 10K - 500K, 1/pk
BioSuite SEC Columns are available in 4.6 mm, 7.5 mm, and 7.8 mm i.d. analytical and 21.5 mm i.d. preparative and guard columns.
Waters Corp DeltaPak C18 Sentry Guard Cartridge, 100Å, 5 µm, 3.9 mm X 20 mm, 1K - 15K, 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.
Advanced Materials Technology HALO 90 Å ES-CN, 2.7 µm, 3.0 x 5 mm, Guard Column 3pk
HALO ES-CN columns made with innovative Fused-Core particle technology for excellent reproducibility and column lifetimes provide fast, high resolution separations. Available in three particle sizes and a wide range of column dimensions, HALO 90 Å ES-CN columns are optimized for high performance in HPLC, UHPLC, and LCMS small molecule applications.
Waters Corp Spherisorb C8 Guard Cartridge, 80Å, 5 µm, 4.6 mm X 10 mm, 3/pk
Spherisorb C8 columns are general purpose, silica-based reversed-phase columns that contain an Octyl ligand. These USP L7 columns are used when you require a less retentive sorbent compared to the Spheriorb ODS columns.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 5 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.
Optimize Technologies OPTI-GUARD™ 1mm Guard Column, DVB (White Label), 5pk
OPTI-GUARD™ sets the standard for extremely low impact, easy to use pre-column protection. Designed for use with analytical (4.6, 3.0 mm i.d.) and narrow-bore (2.1, 1.0 mm i.d.) columns, the patented floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection every time. The best part? It's no larger than a standard fitting. Connecting the OPTI-GUARD™ requires no extra tubing, maintaining the minimal impact philosophy that has made the OPTI-GUARD™ line so popular. As always, custom packing is available. Key Features include: 5 disposable hand-tight holders and cartridges, a ZDV Connection, automatic adjusting to any manufacturer's column, no extra tubing is required for connection, the product does not effect chromatography, and it is no larger than a standard fitting.
Sepax Technologies Inc Sepax HPLC Column GP-C4, 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.
Sepax Technologies Inc Sepax HPLC Column GP-C18, 3 µm, 120 Å, 4 x 10 mm
GP-C18 uses full coverage bonded silica packing, which provides exceptionally high stability. The unique mono-functional bonding chemistry of GP-C18 avoids the formation of multiple C18 layers. Such uniform stationary phase allows the separation to achieve high selectivity and high efficiency.
Waters Corp SEC Guard Column 5µm 500Å 4.6mm ID
SEC Guard Column 5µm 500Å 4.6mm ID. Appropriate for SEC-MALS of adeno-associated virus (AAV) samples.
