Additional Information
Symmetry Silica C18 Prep Guard Cartridge, 100Å, 5 µm, 19 mm X 10 mm, 1/pk HPLC column protection should be one of your top priorities whenever you’re in the lab. Even if you follow proper column cleaning and regeneration procedures, there’s still a chance your Symmetry C18 Column can become fouled over time by particulate contaminants. Luckily, there’s a solution with the Symmetry C18 Prep Guard Cartridge. This guard cartridge removes those contaminants from the mobile phase stream before they enter your column. What’s more, when the cartridge is becoming worn and needs to be replaced, you can do so with another genuine replacement guard cartridge from Waters. Add the Symmetry C18 Prep Guard Cartridge to your workflow now and enjoy enhanced HPLC column lifetimes. How does the Symmetry C18 Prep Guard Cartridge work? Packed with the same column packing material that the Symmetry C18 Column has, this guard cartridge is placed between the mobile phase injector and column to act as an extra step of filtration before any separations occur. To ensure that adding this guard cartridge is chemically and mechanically stable for your workflow, this cartridge also offers the same inner diameter as the Symmetry C18 Column. Plus, if you’re concerned about how adding a cartridge might affect pH resistance, you don’t have to be. The Symmetry C18 Prep Guard Cartridge offers the same pH levels as its corresponding column. The Symmetry C18 Prep Guard Cartridge isn’t all you need to properly install this cartridge into your workflow, though. You still need a 19 mm X 10 mm Prep Guard Holder to hold the cartridge in place. This prep guard holder is required for proper installation of the cartridge. At Waters, we have much more than just Symmetry C18 Prep Guard Cartridges to protect your columns from contamination. We also have full LC-MS systems, quality control reference materials, classic chromatography consumables and everything else you need in order to be successful in the lab.

FAQ
How Do I Install the Symmetry C18 Prep Guard Cartridge (19 mm x 10 mm)? The Symmetry C18 Prep Guard Cartridge must be paired with the Prep Guard Holder (PN# 186008745) to be properly installed between the analytical column and mobile phase injector.
