HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column Bio-C4, Guard cartridge with holder, 3 µm, 300 Å, 2 x 10 mm
Monomeric and fully endcapped Bio-C4 packing is bonded with butyl groups that lead to moderate hydrophobicity. Bio-C4 packings of 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of intact proteins, and natural and synthetic peptides.
Waters Corp ACQUITY UPLC BEH Shield RP18 VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk
ACQUITY BEH Shield RP18 columns complement the ACQUITY 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. 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 Shodex SC-LG Guard Column, 7 µm, 6 mm x 50 mm, 1/pk
Shodex high performance polymeric columns for sugar analysis
Tosoh Bioscience LLC TSKGEL AMIDE-80 GUARD COLUMN
Column, Guard; For 21.5mm I.D. Tosoh TSKgel Amide-80 column; Media: Silica; 21.5mm I.D. x 7.5cm Length
Optimize Technologies EXP™Guard Column Cartridge, 3.0mm x 5mm, SCX, 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.
Waters Corp Shodex KC-G Guard Column, 7 µm, 6 mm x 50 mm, 1/pk
Guard column for Shodex KC-811 column
Waters Corp Spherisorb C1 Guard Cartridge, 80Å, 5 µm, 4.6 mm X 30 mm, 3/pk
Spherisorb C1 columns are classified as USP L13 and are general purpose columns that contain trimethylsilane bonded to silica.
Waters Corp ACQUITY UPLC Peptide BEH C18 VanGuard Pre-column, 300Å, 1.7 µm, 2.1 mm X 5 mm, 1K - 30K, 3/pk
VanGuard pre-columns are the first guard column devices designed for routine use at pressures up to 15000 psi (1030 bar) in applications run on the ACQUITY UPLC System. This specific offering contains Waters patented BEH Technology C18, 300A pore, 1.7um particles based and each batch is specifically QC tested with a peptide map to help ensure consistent performance and increased analytical column life.

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.
