XTerra Shield RP18 Column, 125Å, 3.5 µm, 3.9 mm X 100 mm, 1/pk
Waters' unique embedded polar group technology is used in the general-purpose, hybrid-based, reversed-phase C18 columns known as XTerra RP18 columns to enhance peak shape performance for very basic chemicals. Comparing these first-generation columns to a silica-based column, they offer improved pH stability.
Invest in the Waters XTerra Shield RP18 Column, which has the mechanical strength, extremely spherical shape, purity, pore dimensions, surface area, ability to customize particle size, pore dimensions, surface area, and surface chemistry of its silica equivalents. This is accomplished by utilizing conventional bonding agents, making the use of XTerra Shield RP18 Column versatile. Additionally, it enables lab equipment to work at its best for highly basic substances while maintaining excellent separation efficiency and increased pH stability. The wide pH range that the XTerra Shield RP18 columns can function in (2-12).
You can get beyond the substantial drawbacks of the silica-based reversed-phase packing materials thanks to the XTerra Shield RP18 Column's usage of Waters' proprietary organic/inorganic Hybrid Particle Technology (HPT). At high pH, you can specifically overcome their hydrolytic instability. As a result, the Waters XTerra range of reversed-phase HPLC columns is the first alternative to silica-based column technology that is commercially accessible.
High purity methyl hybrid material is used in the construction of the XTerra Shield RP18 column. This material is produced using a process akin to that used to make high-purity silica, with one significant exception: the XTerra material is created by the mixed condensation of two high purity monomers as opposed to one. The Hybrid Particle Synthesis of the XTerra Shield RP18 columns is carried out using tetraethoxysilane (TEOS) and methyltriethoxysilane (MTEOS).
The XTerra Shield RP18 Columns, like all Waters columns, are produced in accordance with ISO 9001 guidelines, guaranteeing that each stage is carried out to the highest standards and tightest tolerances. Additionally, each column is checked individually to determine how well it performs. Each column comes with a certificate of Batch Analysis and Column Efficiency as additional assurance of its superior quality.
