Additional Information
Symmetry Shield RP18 Prep Column, 100Å, 7 µm, 19 mm X 150 mm, 1/pk For preparative HPLC to be successful, you need an HPLC column that’s ready to separate a wide variety of different compounds. And with the Symmetry Shield RP18 Prep Column, you’ll get that and so much more. For one thing, this reverse-phase column provides a wide and usable pH range to accommodate varying analytes. Plus, when you purchase the Symmetry Shield RP18 Prep Column, you’ll get an HPLC column with reduced silanol activity. This translates to improved peak shape and chromatographic resolution. Tell your lab manager now that you want the Symmetry Shield RP18 Prep Column at your command. What makes Symmetry Shield Columns so special? Firstly, all Symmetry Shield Columns are specifically designed to help you overcome all of the obstacles inherent in preparative HPLC. But even more than that, Symmetry Shield Columns feature the Waters patented embedded polar group technology that shields the silica’s residual silanols. You’ll see that this will only improve peak shape for related assays, as well as improve selectivity. High efficiency, superior selectivity and incredible peak shape for basic analytes at neutral pH; the Symmetry Shield RP18 Prep Column truly offers it all. When was the last time you tested your LC-MS system for performance? Performance benchmarking is hugely important when you’re hard at work in the lab performing assay after assay. Before using the Symmetry Shield RP18 Prep Column, it may be time to test your LC-MS system for performance with neutral compounds. And we make that even easier for you to achieve by offering quality control reference materials to assist system performance checks. Add the Neutrals QC Reference Material to your lab’s procurement list. Reproducible HPLC columns are essential when performing prep HPLC, as you need to constantly reproduce separations to verify data. That’s why the Symmetry Shield RP18 Prep Column was designed to withstand that constant reproducibility. Part of this is in thanks to the rugged column structure and Ehtylene-Bridge Hybrid (BEH) base particle. Ready to transform your preparative HPLC assays for the better? Once you’ve added the Symmetry Shield RP18 Prep Column to your cart, make sure to shop lab equipment to see everything else we have to offer. If you’re an LC-MS expert, you’ll find that we offer a massive selection of products and resources to help push science progressively forward.

FAQ
How Does the Symmetry Shield RP18 Prep Column Achieve Low Silanol Activity? The Symmetry Shield RP18 Prep Column achieves low silanol activity thanks to the embedded polar group technology that shields the silica’s residual silanols.
