Symmetry C18 Sentry Guard Cartridge, 100Å, 5 µm, 3.9 mm X 20 mm, 2/pk
Get enhanced column lifetime by using the Symmetry C18 Sentry Guard Cartridge. The guard cartridge is a type of protective lab equipment that is installed between the injector and the analytical column. It performs by removing the chemical impurities and suspended solids from reaching the analytical column.
The Symmetry C18 Sentry Guard Cartridge is manufactured using the same high-performance packing materials that are used in all of Waters analytical columns. It has been designed and developed especially for situations where increased capacity for biological fluid cleanup and/or temperature control is required.
Like all Waters equipment, the Symmetry C18 Sentry Guard Cartridge is manufactured in a cGMP, ISO 9001 certified plant using ultra-pure reagents. In addition to this, each batch of the Symmetry C18 Sentry Guard Cartridge packing material is tested chromatographically with acidic, basic, and neutral analytes. As always, the results are held to the highest standards and the narrowest specification ranges to assure excellent, reproducible performance every single time.
