Additional Information
XTerra Shield RP18 Column, 125Å, 3.5 µm, 4.6 mm X 50 mm, 1/pk Mechanical strength, extremely spherical shape, purity, pore dimensions, surface area, ability to customize particle size, pore dimensions, surface area, and surface chemistry are all advantages of the Waters XTerra Shield RP18 column. Traditional bonding agents are used to accomplish this. As a result, the XTerra Shield RP18 columns are versatile and capable of providing optimal shape performance for strongly basic chemicals while maintaining good separation efficiency and pH stability. The XTerra Shield RP18 columns have a wide pH range of operation. The XTerra Shield RP18 column's high purity methyl hybrid material is made in a similar way as high-purity silica, with one important difference: the XTerra material is made from the combined condensation of two high purity monomers rather than one. The Hybrid Particle Synthesis of the XTerra Shield RP18 columns is done with tetraethoxysilane (TEOS) and methyltriethoxysilane (MTEOS). The lab equipment is made under ISO 9001 conditions, guaranteeing that each stage is carried out to the highest standards and with the tightest tolerances possible. To determine its performance, each column is carefully tested. Each column comes with a certificate of batch analysis and column efficiency. Shop for this and other lab equipment that is available in our wide selection of chromatographic equipment, all manufactured to the highest standards. The Waters XTerra Shield RP18 reversed-phase HPLC lab equipment uses Waters patented organic/inorganic Hybrid Particle Technology (HPT) to overcome the significant limitations of silica-based reversed-phase packing materials, particularly their hydrolytic instability at high pH, making the Waters XTerra family of reversed-phase HPLC columns the first commercially available alternative to silica-based column technology. Use the XTerra Shield RP18 VanGuard Cartridge, 125Å, 3.5 µm, 3.9 mm X 5 mm, 3/pk in conjunction with the XTerra Shield RP18 Column in order to protect the lab equipment from harm caused by unwanted particulate or chemical materials.
