HPLC Guard Columns and Cartridges
Waters Corp Waters Column, BEH C8, 1.7 μm, 2.1 x 100 mm, VanGuard FIT
BEH Technology columns are a good universal choice for a wide variety of compounds, offering exceptional peak shape for basic analytes at elevated pH, stability across a wide pH range, and high temperatures. These C8 columns are designed for fast methods development and offer less retention compared to C18 columns.
- Trifunctionally bonded BEH particles provide a wide usable pH range (1 to 12) and superior low pH stability.
- Ultra-low column bleed.
- MaxPeak High Performance Surface hardware technology reduces unwanted analyte/surface interactions.
- Minimizes loss of metal-sensitive analytes, including lipids, organic acids, acidic peptides, and oligonucleotides.
- Integrated VanGuard Fit column design protects the column from contaminants and extends its lifetime.
- Improved sensitivity and peak shapes.
- Reduced column conditioning and passivation times.

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.
Optimize Technologies EXPGuard Column Cartridge, 2.1mm x 5mm, C18, 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.

Sepax Technologies Inc Sepax HPLC Column PolyRP-500, Guard cartridge with holder, 10 µm, 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.
