Additional Information
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.

We have all available products, technology, and lab equipment available for online purchase through our online shop, and you are welcome to contact Waters at any time to ask about product specifications or other questions you may have. You may also be interested in the Reversed-Phase QC Reference Material , with a collection of mixtures and standards which allow you to evaluate and benchmark your chromatography system before analysis of critical material. Since this Reversed-Phase QC Reference Material contains compounds that could be challenging to separate, it is a significantly complex reference material mixture and can be used with a variety of column chemistries and dimensions, and system hardware. This kit contains 7 compounds including uracil, butylparaben, naphthalene, propranolol, dipropyl phthalate, acenaphthene, and amitriptyline at pH 7.

FAQ
What Precautions Need To Be Observed With The Symmetry C18 Sentry Guard Cartridge? Only use Waters analytical columns of matching chemistry and particle size with the Symmetry C18 Sentry Guard Cartridge. It is crucial that a high-performance matching column is used to ensure that the resolution is not compromised. Please note that the Symmetry C18 Sentry Guard Cartridge may need to be replaced periodically as determined by the sample contamination. Some indications that the cartridge needs to be replaced include increasing backpressure above a set limit and sudden appearance of split peaks.
