Waters, WAT200675, Symmetry Shield RP8 Sentry Guard Cartridge, 100Å, 5 µm, 3.9 mm X 20 mm, 2/pk

These reversed-phase columns contain Waters patented embedded polar group technology that “shields” the silica’ residual silanol surface from highly basic analytes. The reduced silanol activity for the SymmetryShield RP8 column significantly improves peak shape and resolution.

FAQ
How Does Temperature Affect Liquid Chromatography? Chromatography is a set of equilibrium reactions in which analytes are dissolved in the mobile phase or adsorbed to the column's stationary phase. When the temperature is higher, the analytes are exchanged more quickly between the mobile and stationary phases. As a result, higher temperatures accelerate the analysis. What Are The Operating Limitations Suitable For Symmetry Shield RP8 Sentry Guard Cartridge? The Symmetry Shield RP8 Sentry Guard Cartridge can withstand a maximum pressure of 6000 psi (or 415 Bar), and operate in a range of 2 to 8 pH. It is highly recommended to not run analysis outside of the Sentry Guard Cartridges' limitations or close to them for extended periods of time, and the lab equipment will wear out and its performance and longevity will be negatively impacted.
