HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column Proteomix SAX, NP10, Guard cartridge (No Holder), 2 x 10 mm
Proteomix ion-exchange phases have been innovatively developed for achieving high ion-exchange capacity, a breakthrough technology for non-porous resins. Proteomix packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead with particle size selections of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. The hydrophobic PS/DVB resin surface is totally covered by a hydrophilic coating that eliminates non-specific bindings with biological analytes, leading to high efficiency and high recovery separations for biological molecules.

Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 5 µm, 300 Å, 4 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.
Sepax Technologies Inc Sepax HPLC Column PolyRP-1000, Guard cartridge with holder, 5 µm, 2 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
Sepax Technologies Inc Sepax HPLC Column BR-C18, Guard cartridge with holder, 5 µm, 120 Å, 4 x 10 mm
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents, BR-C18 bonded phases have been innovatively and specially designed to ensure maximum surface coverage and full end-capping, which leads to carbon content as high as 19.0%. The bonding chemistry is completely controlled that results in very reliable column-to-column reproducibility. The maximum surface coverage allows BR-C18 to have exceptional stability, resulting in high pH stability in the range of 1.5 to 10.5.
Waters Corp DeltaPak C4 Radial-Pak Column, 100Å, 15 µm, 8 mm X 100 mm, 1/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.
Waters Corp Shodex DC-G Guard Column, 4.6 mm x 10 mm, 1/pk
Polymeric reverse phase columns for applications requiring broad pH range
Mac-Mod Avantor ACE C18-HL, 90 Å, 3 µm, 3.0/4.6 x 10 mm Guard Cartridges (5/pk)
Avantor ACE Excel UHPLC and HPLC columns are manufactured with 100 Å Ultra-Inert Base Deactivated Silica specifically designed for your HPLC method development needs - Note SuperC18 is 95 Å Avantor ACE HPLC columns are available in a wide range of bonded phases (i.e. C18, C18-AR, C18-PFP, C18-Amide, CN-ES, SuperC18, NH2, C8, C4, Phenyl, AQ, CN and Sil). Avantor ACE Excel UHPLC and HPLC columns are avaialble in 1.7, 2, 3, and 5 µm particle sizes in all analytical column sizes. All Avantor ACE Excel columns are known for their excellent peak shape and batch to batch reproducibility. Columns are packed in 1000 bar UHPLC hardware. Note: Avantor ACE Excel UHPLC guard columns are available for all 1.7 and 2 µm particle sizes across all 2.1 mm - 4.6 mm column ID - Note: H0011 connects directly to the analytical column - Guard column cartridges are available in 3-packs. For 3 and 5 µm Excel columns use same guard systems used for Avantor ACE HPLC analytical columns.
Mac-Mod Avantor ACE UltraCore SuperPhenylHexyl, 95 Å, 4.6 x 5 mm UHPLC Guard Cartridges (3/pk)
Avantor ACE UltraCore solid-core (core-shell) particle columns are ideal for MS work offering improved signal intensity and maximum response. These columns combine high efficiency separations with low back pressure. The Encapsulated Bonding Technology (EBT™) greatly increases the ligand coverage of the silica surface and eliminates the effect of unbonded silanol groups on separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability. Solid Core particle technology provides higher efficiencies per unit back pressure as compared to sub-2-micron UHPLC columns. Columns combine the proven advantages of UHPLC and HPLC columns with Solid Core Particle Technology. Solid-core columns can be used on both UHPLC and HPLC systems. Excellent peak shape and phases stability with extended pH. Highly inert, ultra-low bleed, designed for use with LC/MS compatible buffers. 2.5 and 5 µm particle sizes available.
