Waters, 186006054, XBridge BEH Shield RP18 Column, 130Å, 2.5 µm, 2.1 mm X 75 mm, 1/pk

XBridge BEH Shield RP18 columns complement the XBridge BEH C18 and C8 phases and provide a necessary and powerful tool for HPLC method development. The embedded carbamate group in the bonded phase ligand provides alternate selectivity, especially for phenolic compounds compared to straight chain alkyl columns. Packed in ultra-low dispersion hardware, 2.5 µm eXtended Performance [XP] columns enable exceptional separation performance, robustness and throughput for HPLC assays while enabling a seamless transition path toward UPLC adoption.

Additional Information
XBridge BEH Shield RP18 Column, 130Å, 2.5 µm, 2.1 mm X 75 mm, 1/pk The XBridge BEH Shield RP18 columns are a necessary and powerful tool for HPLC method development, complementing the XBridge BEH C18 and C8 phases. In comparison to straight-chain alkyl columns, the embedded carbamate group in the bonded phase ligand provides alternate selectivity, particularly for phenolic compounds. The XBridge BEH Shield RP18 XP Column was created to complement other XBridge offerings, such as the XBridge BEH C18 and C8 phases, and to provide a useful tool for HPLC method development. In contrast to regular straight-chain alkyl columns, the carbamate group in the bonded phase ligand in the XBridge BEH Shield RP18 XP Column provides alternate selectivity, particularly for phenolic compounds. To achieve superior bases, the XBridge BEH Shield RP18 XP Column is an excellent choice. Because of the embedded Shield Technology, the XBridge BEH Shield RP18 XP Column has reduced silanol interactions with basic analytes. This technology creates a shielding effect in the sample, deactivating interactions with basic analytes and allowing for more symmetrical and efficient peak shapes and peaks. In contrast, other regular C18 columns have poor peak symmetry due to secondary interactions with basic compounds caused by weak cation exchange with residual surface silanols. A seamless transition path to UPLC adoption is made possible by the inclusion of 2.5 µm eXtended Performance [XP] columns in ultra-low dispersion hardware, which provides exceptional separation performance, robustness, and throughput for HPLC assays.

FAQ
What Are The Operational Limitations For The XBridge BEH Shield RP18 XP Column? The XBridge BEH Shield RP18 XP Column is designed to withstand a pressure of 18,000 psi (or 1240 Bar), a pH range of 2 to 11, and a pore size of 130; however, it is always recommended that the maximum range not be exceeded to ensure the best possible column lifetime and effectiveness.
