Engineered for scientists working at the forefront of biopharmaceutical analysis, the BioResolve RP mAb Polyphenyl VanGuard Cartridge (450Å, 2.7 µm, 3.9 mm x 5 mm) is purpose-built to enhance the robustness and lifetime of BioResolve RP mAb Polyphenyl analytical columns. Each cartridge contains superficially porous silica particles with a large 450Å pore size, ideal for intact monoclonal antibody (mAb) and fragment separations. These particles are bonded with a proprietary polyphenyl ligand, optimized for reversed-phase LC and LC-MS workflows targeting IgG mAbs and their subunits.
This part number includes three VanGuard guard cartridges. To operate them effectively, you'll need the BioResolve RP mAb Polyphenyl Column, 450Å, 2.7 µm, 2.1 mm X 150 mm, 1/pk, designed for direct analytical applications.

What does this VanGuard cartridge protect?
This guard cartridge is designed to sit in front of your main analytical column and trap particulates or contaminants before they reach the column, helping to extend its lifespan and maintain analytical performance.
Can I use this guard cartridge for LC-MS analysis?
Yes. It is specifically engineered with a polyphenyl bonded phase for compatibility with reversed-phase LC and LC-MS workflows, especially those involving intact monoclonal antibodies and fragments.
