Symmetry Shield RP18 Column, 100Å, 5 µm, 2.1 mm X 150 mm, 1/pk
Utilize the performance pioneer in the field to offer fundamental compounds in their best shape. The Symmetry Shelter RP18 Column is a reversed-phase column built on Waters' patented embedded polar group technology. It was created to shield (or shield against) extremely basic analytes from the remaining surface silanols on silica. As a result, the lab equipment can give improved peak form and resolution throughout a broad pH range. In addition to this, it causes the column to retain basic chemicals less than the conventional C18 and C8 columns.
Using the Symmetry Shield RP18 Column will lower your lab equipment costs because it is long-lasting. The column's hydrolytic stability of the packing material and the mechanical stability of the packed bed work together to ensure its durability.
A wide pH range is provided by the Symmetry Shield RP18 Column due to its high bonding density and low levels of packing material silanol activity. This helps you to optimize your procedure while maintaining the peak shape while working at neutral or low pH.
Visit our website to learn more about the Symmetry Column product line, which includes variations of the product featured here as well as other products that can meet your analytical needs. You can reach out to our offices and shop for lab equipment on the website.
You can take advantage of the power of tight specification ranges with the Symmetry Shield RP18 Column to attain outstanding reproducibility. This is due to the lab equipment having the narrowest ligand surface coverage (ligand density) in the business and ensuring that resolution shifts are kept to a minimum. This produces findings that are more consistent from batch to batch and column to column.
We recommend that you also use the Waters Symmetry Shield RP18 VanGuard Cartridge, 100Å, 5 µm, 2.1 mm X 5 mm, 3/pk in conjunction with the analytical column in order to increase its efficiency and to improve analysis results. The cartridge works by filtering out any unwanted contaminants from the mobile stream.
