ACQUITY UPLC BEH Shield RP18 Column, 130Å, 1.7 µm, 2.1 mm X 100 mm, 3/pk

When you need selectivites to complement ACQUITY UPLC C18 and C8 phases, embedded polar group columns offer these selectivities along with excellent peak shape for bases and aqueous mobile phase compatibility. By combining Waters’ patented Shield Technology with BEH Technology particles, the ACQUITY UPLC BEG Shield RP18 Column incorporates an embedded carbamate group into the bonded phase ligand. The alternate selectivity and excellent peak shape from the embedded polar group ligand combine with a wide pH range and ultra-efficiency from the 1.7 µm BEH particle to provide a powerful tool for UPLC method development.

Embedded polar group (Shield) RP columns contain stationary phases which combine the hydrophobicity of an alkyl ligand with the hydrophilicity of embedded polar groups. This ability is paired with the rugged and efficient stationary phases available in ACQUITY UPLC BEH columns and the extended lifetimes available under UPLC conditions. As a part of developing the sophisticated lab equipment, Waters designed new column hardware to minimize band broadening and ensure connections without leaks. An innovative frit design was also implemented to keep 1.7 µm particles in the column and out of detectors and MS sources. All of this is completed using proprietary column packing stations and processes that ensure stable packed column beds and reproducibility among columns. Lifetimes can be further extended by using an ACQUITY UPLC BEH Shield RP18 VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk.

All Waters columns are designed to provide consistent results, excellent peak shape, and long column lifetimes. To produce these industry-leading abilities and superior reproducibility between columns and batches, ACQUITY UPLC BEH Shield RP18 columns are manufactured in cGMP, ISO 9002-certified facilities.
