HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column BR-C18, 5 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.
Waters Corp ACQUITY UPLC CSH Fluoro-Phenyl VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk
Designed to maximize selectivity differences, the ACQUITY CSH Fluoro-Phenyl column provides maximum method development freedom, especially when using low pH mobile phases. The non-encapped sorbent provides you with enhanced retention of acidic compounds. The VanGuard pre-column connects directly to the inlet of the ACQUITY UPLC column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
Waters Corp XSelect CSH C18 Prep Guard Cartridge, 130Å, 5 µm, 10 mm X 10 mm, 1/pk
XSelect CSH C18 columns can be used as general purpose columns that provide alternative selectivity compared to other C18 sorbents. Charged Surface Hybrid (CSH) technology helps you overcome column related problems such as peak shape asymmetry and poor loading for basic compounds, column bleed, and slow mobile-phase re-equilibration.
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%.
Waters Corp XTerra MS C18 Prep Guard Cartridge, 125Å, 10 µm, 19 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.
Sepax Technologies Inc Sepax HPLC Column PolyRP-NP3, Guard cartridge with holder, 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.

Waters Corp XTerra MS C18 VanGuard Cartridge, 125à , 2.5 µm, 2.1 mm X 5 mm, 3/pk
XTerra MS C18 VanGuard Cartridge, 125à , 2.5 µm, 2.1 mm X 5 mm, 3/pk
Waters Corp Viridis BEH 2-Ethylpyridine VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk
Designed and tested for the ACQUITY UPC2 system, the Viridis sub-2-µm and 3.5 µm columns demonstrate high efficiency and resolution. The reduction and control of surface silanol activity on Viridis particles delivers, under SFC conditions, excellent peak shapes — without the use of mobile-phase additives — even for well-retained basic achiral compounds.
Waters Corp XBridge Peptide BEH C18 Prep Guard Cartridge, 300Å, 5 µm, 10 mm X 10 mm, 1/pk
The XBridge BEH300 PREP C18 10 µm 10 x 10 mm Guard Column was develeped and designed to extend the life the BEH300, C18, 10 µm, 10mm ID preparative column. The BEH300 PREP C18, 10um packing material used in the Guard Column must also pass the peptide digest, QC test criteria established for the prep column.
