Guard Cartridge E ProteoSil 1.9um, 200-C18 2.1x10mm 2/pk (U)HPLC Guard Cartridges

The ProteoSil 200-C18 pre-column cartridges 10x2.1mm, 1.9µm, are used to protect ProteoSil 200-C18 HPLC columns with an inner diameter of 2.1mm. The 5020-08630 pre-column holder is used to mount them.

Features and Benefits

• Bio-LC column series for proteins, peptides, oligonucleotides, nucleic acids, and biopharmaceutical applications
• High-purity silica with controlled pore sizes of 100 Å, 200 Å, and 300 Å
• Choice between reverse-phase, HILIC, and size-exclusion chromatography
• Stainless steel, PEEK, and bio-inert hardware for various requirements
• Low lot-to-lot variability and consistent quality, even for LC/MS methods

Additional Information

The ProteoSil series is designed for bioseparations in which pore size, modification, and hardware must be specifically tailored to sensitive biomolecules. It is based on a high-purity silica matrix with pore sizes of 100 Å, 200 Å, or 300 Å. Smaller pores are particularly suitable for low-molecular-weight peptides, while 200 Å materials are used for medium-sized peptides and oligonucleotides. For larger proteins, hydrophobic peptides, and antibodies, 300 Å materials are available. In addition, ProteoSil HILIC and ProteoSil SEC round out the series for hydrophilic analytes and size-based separations. Using appropriate ProteoSil pre-column cartridges or guard columns, the analytical column can be protected from particles, strongly adsorbing sample components, and matrix carryover.
