Product Description
The Discovery C18 Supelguard guard cartridges 20x4.0mm, 5µm, are used for the column protection of Discovery C18 HPLC columns. The Supelguard Guard Cartridge Holder 59660-U serves as the holder.
Features and Benefits
- Wide range of selectivities
- Silica, zirconia, and Bio-Wide-Pore phases
- Suitable for RP, specialized RP, and bioanalytics
- Robust method development
- Compatible Supelguard column protection systems
Additional Information
The Discovery Series includes various material platforms and surface chemistries. In addition to classic silica-based reverse-phase columns, high-purity HS phases, pentafluorophenyl, RP-amide, and PEG selectivities, as well as zirconia-based phases, are available. Bio-Wide-Pore variants with larger pores are designed for peptides and proteins. This makes Discovery particularly well-suited for method development when standard C18 selectivity is insufficient or more robust surfaces are required.
