XTerra Shield RP18 Prep Guard Cartridge, 125Å, 10 µm, 19 mm X 10 mm, 1/pk
XTerra Preparative RP18 Columns can exhibit chemical or particulate fouling symptoms over time, but overall column performance concerns can be put to rest thanks to the XTerra Shield RP18 Prep Guard Cartridge. This guard cartridge contains the same packing material that the XTerra Shield RP18 Column has, which allows for a streamlined column protection workflow. What’s more, the preparative guard cartridge seamlessly incorporates into your existing workflow, even offering the same internal diameter as the analytical column so there’ll be no concerns around pressure leaks. Add the XTerra Shield RP18 Prep Guard Cartridge to your lab’s toolkit today.
Scientists across the globe are working to overcome various column protection concerns, like what happens when a column has become fouled by chemical or particulate contaminants. That’s why we’re happy to provide a solution with HPLC guard cartridges. To properly install the XTerra Shield RP18 Prep Guard Cartridge into your existing workflow, make sure to purchase the Prep Guard Holder. Without the Prep Guard Holder, you won’t be able to properly use the preparative guard cartridge.
What is an HPLC guard cartridge?
Placed between the injector and analytical column, the guard cartridge acts an extra step for the mobile phase stream to move through, removing any contaminants that may be in the stream itself. Plus, because the prep guard cartridge always has the same column packing material as the column, the base chemistry remains stable. This especially comes in handy when you need to constantly reproduce assays for data validation. And during method development, the enhanced column protection can even assist in increased sample purification before scaling up.
At Waters, we have guard cartridges, pre-columns and other column protection solutions to match various LC-MS applications. But when you shop lab equipment, you’ll find a truly massive selection of LC-MS products and resources that are invaluable to scientists everywhere. Feel free to browse or ask our team for assistance.
How Do I Install the XTerra Shield RP18 Prep Guard Cartridge?
The XTerra Shield RP18 Prep Guard Cartridge can only be properly installed when the Prep Guard Holder (PN# 186006912) is incorporated into your workflow.
