HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column GP-C18, 3 µm, 120 Å, 4 x 10 mm
GP-C18 uses full coverage bonded silica packing, which provides exceptionally high stability. The unique mono-functional bonding chemistry of GP-C18 avoids the formation of multiple C18 layers. Such uniform stationary phase allows the separation to achieve high selectivity and high efficiency.
Waters Corp SEC Guard Column 5µm 500Å 4.6mm ID
SEC Guard Column 5µm 500Å 4.6mm ID. Appropriate for SEC-MALS of adeno-associated virus (AAV) samples.
Tosoh Bioscience LLC TSKgel UP-SW Aggregate DC Guard Column for 4.6 mm ID column, 3 um, 2 cm L
TSKgel UP-SW Aggregate DC Guard Column for 4.6 mm ID column can be directly connected to the TSKgel UP-SW Aggregate analytical column without tubing between the two columns. A male-type outlet endfitting on the guard column enables the direct connection to the screw-type endfitting of the analytical column.
Trajan Scientific HPLC Reverse Phase Protecol C18 1/EA
C18G x 5 m particle size x 120 pore size 250 mm length x 4 6 mm ID stainless steel with guard ProteCol HPLC column
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 3 µm, 300 Å, 4 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.

Sepax Technologies Inc Sepax HPLC Column HP-Cyano, Guard cartridge with holder, 3 µm, 120 Å, 2 x 10 mm
Synthesized with monomeric and fully endcapped chemistry, HP-Cyano phase is bonded with propylcyano functional group that allows special interaction with polar compounds. The monomeric bonding chemistry enables high efficiency and high resolution separation of peptide, proteins, acidic, neutral and basic organic compound, and pharmaceuticals.
Waters Corp XSelect HSS C18 XP VanGuard Cartridge, 100à , 2.5 µm, 2.1 mm X 5 mm, 3/pk
XSelect HSS C18 XP VanGuard Cartridge, 100à , 2.5 µm, 2.1 mm X 5 mm, 3/pk
Optimize Technologies EXP Guard Column Cartridge, 4.6mm x 5mm, C4, 1.8µm, 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.
