Waters Corp Waters XTerra HPLC Column, 7.8 × 50 mm, 5 μm, Shield RP18
Supplier: Waters Corp 186001154
XTerra HPLC Columns feature first-generation hybrid particle technology, combining silica efficiency with polymer stability. This design enables high-efficiency separations over an expanded pH range, characteristic of polymer particles. The result is a rugged material offering high mechanical strength, efficiency, excellent peak shape for bases, and a wider pH range compared to silica-based particles.
- First-generation hybrid particle (silica co-polymer) stationary phase, utilizing methylene-bridged particles.
- Wider pH range (2–12 for Shield RP18 and Shield RP8) than silica-based particles.
- Spherical particle shape with a 125 Å pore size.
- Homogeneous coverage with less silanols and superior peak shape.
- Facilitates scale-up from analytical to preparative chromatography, allowing for excellent peak shapes for bases and increased mass loading.
