XTerra Shield RP18 Column, 125Å, 3.5 µm, 3 mm X 50 mm, 1/pk

Utilize the XTerra Shield RP18 Column to get around some of the important drawbacks of the silica-based reversed-phase packing materials, particularly their hydrolytic instability at high pH. The lab equipment is made possible by the use of Waters' patented organic/inorganic Hybrid Particle Technology (HPT), which has a number of benefits over conventional silica columns. The first silica-based column technology substitute to be made commercially accessible is the Waters XTerra range of reversed-phase HPLC columns.

XTerra RP18 columns are general purpose, hybrid-based, reversed-phase C18 columns that incorporate Waters patented embedded polar group technology to improve peak shape performance for highly basic compounds. These first-generation columns provide superior pH stability compared to a silica-based column.

With one significant exception, the XTerra material is created from the combined condensation of two high purity monomers as opposed to one, which is how high-purity silica is made. This material is used in the XTerra Shield RP18 Column. The Hybrid Particle Synthesis of the XTerra Shield RP18 Column is carried out using Tetraethoxysilane (TEOS) and Methyltriethoxysilane (MTEOS).

The Waters XTerra Shield RP18 offers many advantages over the traditional silica columns that are currently on the market. These include the capacity to customize particle size, pore diameters, surface area, purity, extremely spherical shape, mechanical strength, and surface chemistry. The lab equipment uses conventional bonding agents to do this. Additionally, it makes it possible for the XTerra Shield RP18 column, a vital piece of all-purpose lab equipment, to maintain high separation efficiency, give optimal shape performance for extremely basic chemicals, and enhance pH stability. With the XTerra Shield RP18 Column, you may work with a variety of pH levels.

Protect your column by opting for the XTerra Shield RP18 VanGuard Cartridge, 125Å, 3.5 µm, 2.1 mm X 5 mm, 3/pk. Made using the exact same packing materials as the columns, the cartridge works by removing any chemical or particulate matter from the mobile stream, increasing the accuracy of the results and the lifetime of the column.
