Waters, WAT200662, Symmetry Shield RP8 Column, 100Å, 5 µm, 4.6 mm X 150 mm, 1/pk

These reversed-phase columns contain Waters patented embedded polar group technology that “shields” the silica’ residual silanol surface from highly basic analytes. The reduced silanol activity for the SymmetryShield RP8 column significantly improves peak shape and resolution.

Additional Information
Symmetry Shield RP8 Column, 100Å, 5 µm, 4.6 mm X 150 mm, 1/pk Leverage the narrowest ligand surface coverage (ligand density) in the industry to get outstanding reproducibility. Utilize the unique feature of narrow specification ranges offered by the Symmetry Shield RP8 Column, to get minimal shifts in resolutions and, thus, more reproducible results from batch-to-batch and column-to-column. The Symmetry Shield RP8 Column exhibits less retention for basic compounds, due to the lower silanol activity than the conventional columns. This makes it an excellent method development tool and a crucial piece of lab equipment. In addition to this, with the Symmetry Shield RP8 Column, you get superior peak shape across the 2-8 pH range, as it has high bonding density and minimal residual silanol activity of packing materials. This gives you the option to choose to work at neutral or low pH to optimize your method without compromising the peak shape. The analytical column will help you in developing new methods faster and improve the laboratory’s productivity by delivering lower levels of detection and quantitation. In applications that require low organic mobile phase conditions, the Symmetry Shield RP8 Column is perfect for use with highly aqueous mobile phases. The column prevents pore dewetting as the embedded polar group maintains the wetted pore surface. This in turn ensures retention of your analyte and eliminates the need for a lengthy re-wetting and column re-equilibration process. Since the Symmetry Shield RP8 Column offers the combination of two main factors that impact the column’s lifetime, the hydrolytic stability of the packing material and mechanical stability of the packed bed. This guarantees that the column will last you a long time and reduce your lab equipment cost, as well as continually deliver optimized performance. Shop for lab equipment such as the Reversed-Phase QC Reference Material , which is intended to benchmark the chromatography system before analysis of critical material and contains 7 compounds including uracil, butylparaben, naphthalene, propranolol, dipropyl phthalate, acenaphthene, and amitriptyline at pH 7. The Reference Material is a specially formulated mix that includes a void marker, neutral, acidic, and basic compounds that have been tested and chosen because they provide an excellent benchmark, offer good peak shape on UV, and are acceptable for use on a variety of columns.

FAQ
What Pressure Is Recommended For Use With The Symmetry Shield RP8 Column? Though the Symmetry Shield RP8 Column can tolerate pressures of up to 6,000 psi, the recommended operating pressure range is between 4,000-5,000 psi in order to maintain the optimum column and system lifetimes.
