HPLC Guard Columns and Cartridges
Waters Corp Symmetry C4 Sentry Guard Cartridge, 300Å, 3.5 µm, 2.1 mm X 10 mm, 2/pk
Symmetry columns continues to set the standard for HPLC drug assays, giving you confidence in the long-term compliance of your HPLC methods. No need to compromise on peak shape, selectivity, column-to-column and batch-to-batch reproducibility, or other critical performance characteristics. Available in a variety of particle sizes, chemistries and dimensions.
Sepax Technologies Inc Sepax HPLC Column GP-C8, 5 µm, 120 Å, 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 GP-Phenyl, Guard cartridge with holder, 5 µm, 120 Å, 2 x 10 mm
GP-Phenyl packing materials are bonded with propyl phenyl groups that enable special interaction with ring structured compounds. The monomeric bonding chemistry gives high efficiency and high resolution separations. GP-Phenyl phase is suitable for separations of acidic, neutral and basic organic compounds, as well as pharmaceuticals.

Waters Corp XTerra Shield RP18 Prep Guard Cartridge, 125Å, 5 µm, 19 mm X 10 mm, 1/pk
XTerra Preparative RP18 columns are hybrid-based, reversed-phase C18 columns that incorporate Waters patented embedded polar group technology to improve peak shape performance for highly basic compounds. These first generation columns provide superior pH stability compared to a silica-based column. This product needs to be used in conjunction with other parts.

120 EC-C18, 2.1 x 5 mm, 2.7 m, guard column, 3/pk
Sepax Technologies Inc Sepax HPLC Column Proteomix HIC Propyl-NP5, Guard cartridge with holder, 4 x 10 mm
Proteomix HIC columns are specially designed for high resolution and high efficiency separations of proteins, monoclonal antibodies (mAbs), antibody drug conjugates (ADCs), oligonucleotides and peptides via a hydrophobic interaction chromatography (HIC) mechanism. Utilizing proprietary surface technologies, Proteomix HIC-NP resin is made of non-porous polystyrenedivinylbenzene (PS/DVB) beads with narrow-dispersed particle size distribution. As shown in figure below, the PS/DVB bead is modified with alkyl groups or aryl groups that provide hydrophobic interaction with analytes. Proteomix HIC-NP resin is highly rigid and mechanically stable. In comparison to silica-based HIC phase media, Proteomix HIC-NP phases have advantages for biomolecule separations with a wide pH range (2-12) and high chemical stability.
Sepax Technologies Inc Sepax HPLC Column SRT-10 SEC-100, 10 µm, 21.2 x 10 mm, Guard cartridge with holder
Utilizing proprietary surface technologies, SRT-10 and SRT-10C SEC phases are made of uniform, hydrophilic, and neutral nanometer thick films chemically bonded on high purity and mechanically stabilized 10 µm silica. The well-controlled surface chemistry results in excellent lot-to-lot reproducibility. Our unique bonding chemistry, coupled with the maximized bonding density, allows SRT-10 and SRT-10C SEC phases to provide high stability and negligible non-specific interactions. SRT-10 and SRT-10C packings have large pore volume, resulting in high separation resolution. Typical applications for SRT-10 and SRT-10C columns include separation and detection of biological molecules and water-soluble polymers in aqueous buffers.
Waters Corp MassPrep Phenyl Guard Column, 1000Å, 20 µm, 2.1 mm X 10 mm, 10K - 500K, 2/pk
XTerra MS C18 columns are general purpose, hybrid-based, reversed-phase C18 columns that are designed to be compatible with mass spectrometry applications. These first generation columns provide superior pH stability compared to a silica-based column.
Waters Corp XTerra Shield RP8 Prep Guard Cartridge, 125Å, 5 µm, 7.8 mm X 10 mm, 1/pk
XTerra Preparative RP8 columns are hybrid-based, reversed-phase C8 columns that incorporate Waters patented embedded polar group technology to improve peak shape performance for highly basic compounds. These first generation columns provide superior pH stability compared to a silica-based column. This product needs to be used in conjunction with other parts.

Waters Corp XTerra MS C18 Prep Guard Cartridge, 125Å, 10 µm, 7.8 mm X 10 mm, 1/pk
XTerra Prep columns bring the benefits of Hybrid Particle Technology to isolation and purification applications in discovery and development laboratories. XTerra Prep MS columns possess our patented Hybrid Particle Technology, with particles engineered specifically for prep. It allows you to routinely operate at pH 1-12 so you can load up to 60X more onto the column. More capacity results in fewer injections for the same amount of pure material or more material with the same number of injections. In the discovery world, this greater capacity means you can use a shorter column, producing the same amount of material in half the time.
