Waters, 186000108, Symmetry Shield RP18 Column, 100Å, 5 µm, 3.9 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 RP18 column significantly improves peak shape and resolution.

Additional Information
Symmetry Shield RP18 Column, 100Å, 5 µm, 3.9 mm X 150 mm, 1/pk Use the industry leader of performance to deliver peak shape of basic compounds. The Symmetry Shield RP18 Column is a reversed-phase column that is based on Waters’ patent embedded polar group technology that has been designed to protect (or ‘shield’) the silica’s residual surface silanols from highly basic analytes. This makes it possible for the lab equipment to deliver improved peak shape and resolution over a wide pH range. It also makes the column exhibit less retention of basic compounds than the traditional C18 and C8 columns. With the Symmetry Shield RP18 Column, you can leverage the power of narrow specification ranges to get exceptional reproducibility with the Symmetry Shield RP18 Column. This is because the lab equipment offers the narrowest ligand surface coverage (ligand density) in the industry and ensures that you get minimal shifts in resolutions. This gives more reproducible results from batch-to-batch and column-to-column. Reduce your lab equipment cost with the Symmetry Shield RP18 Column, as it is guaranteed to last you a long time. The longevity is assured by the combination of two main factors in the column, the hydrolytic stability of the packing material and mechanical stability of the packed bed. The Symmetry Shield RP18 Column offers a wide pH range (2-8) as it has high bonding density and minimal residual silanol activity of packing materials. This enables you to work at neutral or low pH to optimize your method without compromising the peak shape. Browse through our website to find out more about the range of Symmetry Column, including variants of the product listed here as well as others that may suffice your analytical needs. Through the website, you can also contact our offices and shop for lab equipment . You may also be interested in the Symmetry Shield RP18 VanGuard Cartridge, 100Å, 5 µm, 3.9 mm X 5 mm, 3/pk . Manufactured using identical packing materials as the Symmetry Shield RP18 Column, the VanGuard Cartridge is ideally suited to protect the analytical column. It works by being attached to the column and prevents any chemical or particulate matter from harming the column or interfering with the analysis results.

FAQ
When Does The Symmetry Shield RP18 VanGuard Cartridge Need To Be Changed? A sudden appearance of split peaks and an increase in backpressure are usually signs that the VanGuard Cartridge needs to be replaced.
