XTerra Shield RP18 Prep Column, 125Å, 10 µm, 7.8 mm X 300 mm, 1/pk
Invest in the Xterra Shield RP18 Column to increase peak shape performance for highly basic compounds quickly and easily. A general-purpose, hybrid-based, reversed-phase C18 column with Waters patented embedded polar group technology is used in the lab. When compared to a silica-based column, the XTerra Shield RP18 column is a first-generation column that delivers greater pH stability.
Using the XTerra Shield RP18 Column, overcome the significant limitations of silica-based reversed-phase packing materials, particularly their hydrolytic instability at high pH. Waters' unique organic/inorganic Hybrid Particle Technology (HPT) is used in the lab equipment, allowing it to offer various advantages over traditional silica columns. The Waters XTerra range of reversed-phase HPLC columns is the first commercially available silica-based column alternative.
The Waters XTerra Shield RP18 offers significant advantages over traditional silica columns on the market. Mechanical strength, extremely spherical shape, purity, pore dimensions, surface area, particle size tailoring, pore dimensions, surface area, and surface chemistry are among them. Traditional bonding agents are used by the lab equipment to achieve this. It also allows the XTerra Shield RP18 column, an important piece of general-purpose laboratory equipment, to achieve optimal shape performance for extremely basic substances, maintain high separation efficiency, and increase pH stability. You can operate within a wide pH range with the XTerra Shield RP18 Column (2-12).
The XTerra Shield RP18 Column uses a high purity methyl hybrid material that is 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 Column. Like all lab equipment manufactured by Waters, the XTerra Shield RP18 Column is also manufactured under ISO 9001 conditions, ensuring each step is conducted to the highest standards and narrowest tolerances.
Browse through the Waters brochure or visit our website to shop for lab equipment as per your laboratory needs. Along with the XTerra Shield RP18 Prep Column, you should also look into the Terra Shield RP18 Prep Guard Cartridge, 125Å, 10 µm, 7.8 mm X 10 mm, 1/pk. XTerra Preparative RP18 columns are hybrid-based, reversed-phase C18 columns that provide superior pH stability compared to silica-based columns. This product needs to be used in conjunction with other parts.
Under What Operational Conditions May One Use The XTerra Preparative RP18 Column?
The XTerra Preparative RP18 columns have a broad pH range of 2 to 12, with a temperature limitation of 60 C and a maximum pressure setting of 6000 psi (or 415 Bar).
