HPLC Guard Columns and Cartridges
Mac-Mod Evosphere Diphenyl, 100 Å, 5 µm, 30.0 x 10 mm Monodisperse Fully Porous Particle Guard Cartridge
Evosphere UHPLC and HPLC columns are 100 A Monodispersed Fully Porous Silica-based columns designed to combine the benefits of Fully Porous and Core-Shell particle technology into an improved particle design and morphology that brings cutting-edge loading capacity to ultra-high-resolution particle columns. The Monodispersed Particles provide similar efficiency to Core-Shell products when comparing them directly via particle size matching and significantly increase loadability which allows ultra-high resolution analytical separations to scale to preparative separations for isolation work if needed. The bonded phase chemistries are exciting as well to maximize selectivity with novel C12 bonded phase, 2 multi-modal C18/AR, and C18/PFP bonded phases, an extended and stabilized phenyl funtionality in the Diphenyl bonded phase, a polar endcapped AQUA phase, a Phenyl-Hexyl phase, a propyl PFP phase and the RP18-Amide bonded phases which is great for doing bases at low pH.
Sepax Technologies Inc Sepax HPLC Column HP-C18, 3 µm, 120 Å, 2 x 10 mm
HP-C18 uses full coverage bonded silica packing, which provides high stability. Compatible with 100% aqueous mobile phase and suitable for separations of acidic, neutral and basic organic compounds, as well as pharmaceuticals and peptides. ODS monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
Sepax Technologies Inc Sepax HPLC Column Proteomix WAX, NP10, 4 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 Polar-Imidazole, Guard cartridge with holder, 10 µm, 120 Å, 4 x 10 mm
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents, Polar-Imidazole phase is bonded with imidazole functional groups. With a polar and N-containing ring structure, Polar-Pyridine phase is a weak base and adequate for many applications, such as pharmaceuticals, peptides, sugars, and nucleotides.
Agilent Technologies AGILENT INFINITYLAB POROSHELL
120 EC-C18, 2.1 x 5 mm, 2.7 m, guard column, 3/pk
Mac-Mod Avantor ACE C18, 100 A, 5 um, 3.0/4.6 x 10 mm Guard Cartridges (5/pk)
Avantor ACE HPLC columns are manufactured with 100 A Ultra-Inert Base Deactivated Silica specifically designed for your HPLC method development needs. Avantor ACE HPLC columns are available in a wide range of bonded phases (including C18, C18-AR, C18-PFP, C18-HL, C8, C4, Phenyl, AQ, CN and Sil) - Note C18-HL is 95 A. Avantor ACE HPLC columns are available in 3, 5 and 10 um particle sizes and a wide range of column IDs and column lengths including nano, capillary, microbore, analytical, semi-preparative and preparative formats. All Avantor ACE columns are known to deliver excellent peak shape and verified batch to batch reproducibility. Columns are packed in 275 bar HPLC hardware. Note: Avantor ACE HPLC guard columns are available for all 3.0 and 5.0 um particle sizes across 2.1 mm to 4.6 mm column ID - Note: C0001 male/male union is needed to connect guard holder (H0001) to the analytical column. Avantor ACE UHPLC alternatives columns are available under the ACE Excel brand.
Sepax Technologies Inc Sepax HPLC Column BR-C18, Guard cartridge with holder, 3 µm, 120 Å, 2 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.
Sepax Technologies Inc Sepax HPLC Column PolyRP-NP1.7, Guard cartridge with holder, 4 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.
Mac-Mod HydroBond 100 Å, Guard Holder
Hydrobond is designed for polar retention of highly polar analytes in RPLC. These columns provide reproducible results, column to column, lot to lot.
