XBridge BEH Shield RP18 Sentry Guard Cartridge, 130Å, 5 µm, 4.6 mm X 20 mm, 2/pk
To properly protect your XBridge BEH Shield RP18 Column from particulate contaminants, you need to first purify your samples as much as possible. But what about the miniscule contaminants that aren’t filtered out during sample prep?
That’s where the XBridge BEH Shield RP18 Sentry Guard Cartridge comes into consideration. This state-of-the-art guard cartridge stops contaminants in their path, removing them from the mobile phase stream before they reach your precious column. What’s more, when the guard cartridge becomes worn and needs to be replaced, you can do so with a genuine replacement from Waters Corporation. Add the XBridge BEH Shield RP18 Sentry Guard Cartridge to your workflow and enjoy enhanced column protection that results in longer column lifetimes.
How does the XBridge BEH Shield RP18 Sentry Guard Cartridge work?
Placed between the mobile phase injector and your column, the guard cartridge acts as an extra filtration step before separations are completed. But for the guard cartridge to be properly installed, you also need the Holder Kit for Cartridge and Guard Columns. This holder kit is required for proper sentry guard cartridge installation, otherwise the guard cartridge won’t be able to be incorporated into your workflow. Make sure to add both the guard cartridge and holder kit to your cart before checking out.
Speaking of column protection, it’s incredibly important that anything you add to your workflow upholds mechanical and chemical stability. That’s why the XBridge BEH Shield RP18 Sentry Guard Cartridge is packed with the same packing material as the XBridge BEH Shield RP18 Column and offers the same inner diameter as the column. That way there’s minimal chance of backpressures to leak or samples to leak out as well.

How Do I Install the XBridge BEH Shield RP18 Prep Guard Cartridge?
