Symmetry Shield RP18 Sentry Guard Cartridge, 100Å, 3.5 µm, 3.9 mm X 20 mm, 2/pk
You may extend the life of your columns by using the Symmetry Shield RP18 Sentry Guard Cartridge. The Sentry Cartridge, which sits between the injector and the analytical column, is a piece of laboratory safety equipment. Chemical pollutants and suspended particles are kept out of the analytical column with the installation of the Symmetry Shield RP18 Sentry Guard Cartridge. In these reversed-phase columns, Waters' unique embedded polar group technology "shields" the remaining silanol surface from very basic analytes. The lowered silanol activity of the Symmetry Shield RP18 Sentry Guard Cartridge greatly improves peak shape and resolution.
In the Symmetry Shield RP18 Sentry Guard Cartridge, Waters uses the same high-performance packing materials as in all of their analytical columns. It was designed for situations that necessitate increased capacity for biological fluid cleanup and/or temperature control. The Symmetry Shield RP18 Sentry Guard Cartridge has a 15 percent carbon load, a particle size of 5 m, and a pore size of 100.
The Symmetry Shield RP18 Sentry Guard Cartridge, like other Waters products, is created with ultra-pure reagents in a cGMP, ISO 9001-certified facility. Each batch of Symmetry Shield RP18 Sentry Guard Cartridge packing material is also chromatographically tested with acidic, basic, and neutral analytes. To achieve good, consistent, and repeatable performance, the findings are held to the highest standards and the smallest specification ranges possible.
