HPLC Guard Columns and Cartridges
Waters Corp µBondapak Amino (NH2) Sentry Guard Cartridge, 125Å, 10 µm, 3.9 mm X 20 mm, 2/pk
If your method calls for µBondapak packings, there is only one µBondapak packing material. Many companies claim to have columns with µBondapak-like selectivity but not one has ever passed Waters stringent QC batch test. Waters set the standard for reproducible, high-performance chromatographic columns. Waters µBondapak columns are still the most widely referenced and requested columns in the world.
Waters Corp DeltaPak C18 Radial-Pak Column, 100Å, 15 µm, 47 mm X 300 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 Spherisorb ODS2 Guard Cartridge, 80Å, 5 µm, 4.6 mm X 10 mm, 3/pk
Spherisorb ODS2 columns are general purpose, silica-based, reversed-phase C18 columns. The ODS2 packing features intermediate ligand density with a specified carbon load of 11.5%.

XSelect HSS PFP XP VanGuard Cartridge, 100 à , 2.5 µm, 2.1 mm X 5 mm, 3/pk
Waters Corp Symmetry C18 VanGuard Cartridge, 300à , 5 µm, 2.1 mm X 5 mm, 3/pk
Symmetry C18 VanGuard Cartridge, 300à , 5 µm, 2.1 mm X 5 mm, 3/pk
Optimize Technologies EXP™Guard Column Cartridge, 4.6mm x 5mm, C4, 3µm, 3pk
The EXP™ Guard Column cartridge system is rated to 15,000psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP™ Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn™ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/ outlet. The combination of low-dispersion and ultra high-pressure capabilities provides effective protection with negligible effects on retention time, plate count, and peak shape. Use with EXP™ Direct Connect and In-line Holders.
Sepax Technologies Inc Sepax HPLC Column PolyRP-NP3, 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 PolyRP-100, 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 Bio-C8, 5 µm, 300 Å, 2 x 10 mm
Bio-C8 phase is made of monomeric and fully endcapped chemistry. The uniform stationary phase allows the separation to achieve high selectivity and high efficiency. Bio-C8 packings of 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins.
Sepax Technologies Inc Sepax HPLC Column Polar-Imidazole, 3 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.
