Waters Corp XTerra Shield RP18 Sentry Guard Cartridge, 125Å, 5 µm, 3 mm X 20 mm, 2/pk
XTerra RP18 columns are general purpose, hybrid-based, reversed-phase C18 columns that incorporate Waters patented embedded polar group technology to improve peak shape performance for highly basic compounds. These first generation columns provide superior pH stability compared to a silica-based column.
Waters Corp Waters Symmetry Shield RP18 Prep Guard Cartridge, 100Å, 5 μm
This reversed-phase Prep Guard Cartridge incorporates embedded polar group technology, which shields the silica's residual silanol surface from highly basic analytes. The reduced silanol activity significantly improves peak shape and resolution. This product is designed to be used as part of a preparative HPLC workflow. A Prep Guard Cartridge serves to protect analytical or preparative columns by removing contaminants from samples.
- Embedded polar group technology shields the silica's residual silanol surface from highly basic analytes.
- Improved peak shape and resolution is achieved through reduced silanol activity.
- Protects analytical or preparative columns by removing contaminants from samples.
- Reduced silanol activity is important for LC-MS analysis.
- Narrow column specification reduces data variation.
- Can be used with peptide applications.
