The Discovery HS C18 Supelguard guard cartridges 20x4.0mm, 3µm, are used for the column protection of Discovery HS C18 HPLC columns. The Supelguard Guard Cartridge Holder 59660-U serves as the holder.
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.
Discovery is a registered trademark of the manufacturer Merck KGaA, Darmstadt, Germany.
