HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 5 µm, 300 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.

They are packed in Stainless Steel Tubes and have Stainless Steel Frits that are pressed into PEEK Frit Caps. These Guard Column Cartridges must be used with a Guard Column Holder.
Waters Corp XBridge Peptide BEH C18 VanGuard Cartridge, 130Å, 2.5 µm, 3.9 mm X 5 mm, 3/pk
The XBridge Peptide BEH C18 130A C18 columns are optimized and QC tested for peptide separations. The small-pore (130Å) trifunctionally bonded BEH particle offers the widest usable pH range, superior low pH stability, and ultra-low column bleed for proteomic, peptide mapping, and synthetic peptide applications. ;This Part Number is for the appropriate VanGaurd Cartridge, designed to protect either the 3.9mm or 4.6mm ID analytical column, and requires the reuable Universal Guard Cartridge Holder (Part Number 186007949)
Mac-Mod HydroBond AQ C8, 100 Å, 5 µm, 3.2 x 10 mm Guard Cartridges (5/pk)
Hydrobond is designed for polar retention of highly polar analytes in RPLC. These columns provide reproducible results, column to column, lot to lot.
Optimize Technologies OPTI-GUARD 1mm Guard Column, Cyano (CN), (Blue Label), 5pk
OPTI-GUARD™ sets the standard for extremely low impact, easy to use pre-column protection. Designed for use with analytical (4.6, 3.0 mm i.d.) and narrow-bore (2.1, 1.0 mm i.d.) columns, the patented floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection every time. The best part? It's no larger than a standard fitting. Connecting the OPTI-GUARD™ requires no extra tubing, maintaining the minimal impact philosophy that has made the OPTI-GUARD™ line so popular. As always, custom packing is available. Key Features include: 5 disposable hand-tight holders and cartridges, a ZDV Connection, automatic adjusting to any manufacturer's column, no extra tubing is required for connection, the product does not effect chromatography, and it is no larger than a standard fitting.
Mac-Mod Evosphere PFP, 100 Å, 5 µm, 30.0 x 10 mm Monodisperse Fully Porous Particle Guard Cartridge
Evosphere UHPLC and HPLC columns are 100 A Monodispersed Fully Porous Silica-based columns designed to combine the benefits of Fully Porous and Core-Shell particle technology into an improved particle design and morphology that brings cutting-edge loading capacity to ultra-high-resolution particle columns. The Monodispersed Particles provide similar efficiency to Core-Shell products when comparing them directly via particle size matching and significantly increase loadability which allows ultra-high resolution analytical separations to scale to preparative separations for isolation work if needed. The bonded phase chemistries are exciting as well to maximize selectivity with novel C12 bonded phase, 2 multi-modal C18/AR, and C18/PFP bonded phases, an extended and stabilized phenyl funtionality in the Diphenyl bonded phase, a polar endcapped AQUA phase, a Phenyl-Hexyl phase, a propyl PFP phase and the RP18-Amide bonded phases which is great for doing bases at low pH.
