Additional Information
XTerra Shield RP18 Column, 125Å, 5 µm, 4.6 mm X 100 mm, 1/pk Use the general-purpose, hybrid-based, reversed-phase XTerra Shield RP18 Column that incorporates Waters patented embedded polar group technology in order to deliver improved peak shape performance for highly basic compounds. Compared to a silica-based column, the first generation XTerra Shield RP18 Column provides superior pH stability. As the XTerra Shield RP18 Column uses the Waters patented organic/inorganic Hybrid Particle Technology (HPT), it enables you to overcome the significant limitations of the silica-based reversed-phase packing materials. Specifically, you can overcome their hydrolytic instability at high pH. This makes the Waters XTerra family of reversed-phase HPLC columns the first commercially available alternative to silica-based column technology. Invest in the Waters XTerra Shield RP18 Column which offers key advantages of its silica counterparts including mechanical strength, highly spherical shape, purity, pore dimensions, surface area, ability to tailor particle size, pore dimensions, surface area, and surface chemistry. This is achieved by leveraging traditional bonding agents and makes the application of XTerra Shield RP18 Column general-purpose. It also enables the lab equipment to deliver peak shape performance for highly basic compounds, maintaining high efficiency of separation and improved pH stability. The XTerra Shield RP18 columns can operate within a wide-scale pH range (2-12). Like all Waters columns, the columns are manufactured under ISO 9001 conditions, ensuring each step is conducted to the highest standards and narrowest tolerances. In addition to this, every column is individually tested to ascertain its performance. Certificates of Batch Analysis and Column Efficiency are also provided with each column to guarantee its quality. The XTerra Shield RP18 column is made using high purity methyl hybrid material, produced through a method similar to how high-purity silica is manufactured with one major difference: that the XTerra material is formed from the mixed condensation of two high purity monomers instead of one. Tetraethoxysilane (TEOS) and methyltriethoxysilane (MTEOS) are used to perform the Hybrid Particle Synthesis of the XTerra Shield RP18 columns.

FAQ
What Is Meant By Hydrolytic Stability? Hydrolytic stability refers to the resistance of a cured polymer material to reverting to a semisolid or liquid form when exposed to high humidity and temperature.
