Product Description

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 RP18 column significantly improves peak shape and resolution.

Symmetry Shield RP18 Column, 100Å, 3.5 µm, 2.1 mm X 150 mm, 1/pk

Using the Symmetry Shield RP18 Column, you can benefit from the power of narrow specification ranges to get outstanding reproducibility. The lab equipment is unique in its ability to provide the narrowest ligand surface coverage (ligand density) in the industry. The Symmetry Shield RP18 Column is reversed-phase and contains Waters patented embedded polar group technology that “shields” the silica’ residual silanol surface from highly basic analytes. This reduced silanol activity ensures that you get minimal shifts in resolutions and, thus, more reproducible results from batch-to-batch and column-to-column. Additionally, the reduced silanol activity also significantly improves peak shape.

Reduce the high cost of lab equipment by adding the Symmetry Shield RP18 Column in your lab equipment collection as the analytical column is guaranteed to last you a long time, minimizing the need for equipment replacement. The Symmetry Shield RP18 Column achieves this by optimizing performance and offering a strong 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.

The Symmetry Shield RP18 Column works across the 2-8 pH range and offers a superior peak shape. This wide usable pH range is offered by the column due to its high bonding density and minimal residual silanol activity of packing materials. This means that you can choose to work at neutral or low pH to optimize your method without compromising the peak shape. In addition to this, you can use the Symmetry Shield RP18 Column to develop new methods faster and improve the laboratory’s productivity by delivering lower levels of detection and quantitation.

Deliver the same, reproducible chromatographic results over the life of a new drug product through the Symmetry Shield RP18 Column, as the lab equipment is ideally suited for applications such as the establishment of new analytical methods for the latest pharmaceutical and biopharmaceutical products as it offers exceptional reproducibility.

The Symmetry Shield RP18 column is ideally suited to be an excellent method development tool because, when it is compared to the traditional C18 and C8 columns, the Symmetry Shield RP18 column has silanol activity which results in less retention for basic compounds.

Invest in the Symmetry Shield RP18 VanGuard Cartridge, 100Å, 3.5 µm, 2.1 mm X 5 mm, 3/pk so you can ensure that your analytical continues to give outstanding results.

Is C18 Polar Or Non-Polar?

C18 columns are "reverse phase," often used with more polar solvents such as water, methanol, or acetonitrile. The stationary phase is a nonpolar hydrocarbon, whereas the mobile phase is a polar liquid.
