HPLC Guard Columns and Cartridges
Advanced Materials Technology HALO 90 Å PCS Phenyl-Hexyl, 2.7um, 3.0 mm x 5mm, Guard Column 3pk
Built upon proven Fused-Core technology for speed and efficiency, the HALO PCS column products are positively charged surface chemistries designed to deliver improved peak shapes for basic compounds observed with standard Phenyl-Hexyl chemistry. Ideal for use with low ionic strength mobile phases, HALO PCS maintains peak symmetry at higher loading capacities and provides alternate selectivities from Phenyl-Hexyl bonded phases. The columns are optimized to deliver performance for reproducible, high efficiency LC and LCMS separations.
Waters Corp µBondapak C18 Radial-Pak Guard, 125Å, 10 µm, 25 mm X 10 mm, 2/pk
µBondapak C18 columns are general purpose, silica-based, reversed-phase C18 columns that are based on 10 µm particle technology. As a starting point for preparative chromatography, no other column can provide the balance between resolution, throughput and cost.

Waters Corp XTerra MS C18 Sentry Guard Cartridge, 125Å, 3.5 µm, 2.1 mm X 20 mm, 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 XBridge BEH Shield RP18 Sentry Guard Cartridge, 130Å, 5 µm, 3 mm X 20 mm, 2/pk
XBridge BEH Shield RP18 columns complement the XBridge BEH C18 and C8 phases and provide a necessary and powerful tool for HPLC method development. The embedded carbamate group in the bonded phase ligand provides alternate selectivity, especially for phenolic compounds compared to straight chain alkyl columns.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 3 µm, 200 Å, 2 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.
