Symmetry Shield RP8 VanGuard Cartridge, 100Å, 5 µm, 3.9 mm X 5 mm, 3/pk
By eliminating particle pollution from the mobile phase stream, SymmetryShield RP8 VanGuard Cartridges are used to increase analytical column lifetime and performance. All 3.9 mm and 4.6 mm I.D. Symmetry Shield RP8 analytical columns with 5 µm sorbent particles are well-protected by this cartridge.
You may make your columns last longer by using Symmetry Shield RP8 VanGuard Cartridges. The guard cartridge, which is a part of the safety equipment for laboratories, is placed between the injector and the analytical column. Chemical pollutants and suspended particles are prevented from entering the analytical column with the installation of the Symmetry Shield RP8 VanGuard Cartridges. In these reversed-phase columns, the remaining silanol surface is "safeguarded" against very basic analytes thanks to Waters' innovative embedded polar group technology. Peak shape and resolution are considerably improved by the Symmetry Shield RP8 column's reduced silanol activity.
The Symmetry Shield RP8 VanGuard Cartridges from Waters are packed with the same high-performance materials as their analytical columns. It was made especially for situations when increased temperature control and/or biological fluid cleanup capabilities are needed.
Similar to most Waters products, the Symmetry Shield RP8 VanGuard Cartridges are produced in a cGMP, ISO 9001-certified facility using ultra-pure reagents. Each batch of packing material for Symmetry Shield RP8 VanGuard Cartridges is additionally chromatographically tested utilizing neutral, acidic, and basic analytes. To guarantee great, consistent, and repeatable performance, the findings are held to the highest standards, and the narrowest specification ranges, as always.
You will be able to shop for lab equipment straight from our website, and you will also have the option of contacting a member of our global staff for assistance with any questions, issues, or general lab equipment help as needed.
You might want to check out the Symmetry Shield RP8 Column, 100Å, 3.5 µm, 4.6 mm X 150 mm, 1/pk; These reversed-phase columns use Waters' patented embedded polar group technology, which acts as a "shield" against extremely basic analytes on the leftover silanol surface of silica. Peak form and resolution are considerably enhanced by the SymmetryShield RP8 column's reduced silanol activity.
How Does Liquid Chromatography Affect Temperature?
Analytes are either dissolved in the mobile phase or adsorbed to the stationary phase of the column during the equilibrium reactions that make up chromatography. The exchange of analytes between the mobile and stationary phases happens more quickly at higher temperatures. Higher temperatures hence speed up the analysis.
