XTerra Hybrid Shield RP18 Method Validation Kit, 125Å, 5 µm, 4.6 mm X 250 mm, 3/pk
Three XTerra RP 18 columns filled with three distinct batches of sorbent make up the XTerra Hybrid Shield RP18 Method Validation Kit. The general-purpose, hybrid-based, reversed-phase C18 columns known as XTerra RP18 columns utilize Waters' distinctive embedded polar group technology to improve peak shape performance for extremely basic compounds. These first-generation columns provide better pH stability when compared to silica-based columns.
The Waters XTerra Shield RP18 Columns feature the same silica-equivalent mechanical strength, very spherical shape, purity, pore dimensions, surface area, capacity to tailor particle size, and surface chemistry. The XTerra Shield RP18 Column can be used in a variety of ways because this is accomplished by using common bonding agents. Furthermore, it improves the effectiveness of separation and pH stability of lab equipment, allowing it to function well for very basic compounds. The XTerra Shield RP18 columns' broad pH range of operation (2-12).
The silica-based reversed-phase packing materials have significant disadvantages that can be overcome by employing the columns from the XTerra Hybrid Shield RP18 Method Validation Kit. This is possible because the XTerra Shield RP18 Column utilizes Waters' patented organic/inorganic Hybrid Particle Technology (HPT). You can specifically avoid their hydrolytic instability at high pH levels. As a result, the Waters XTerra line of reversed-phase HPLC columns is the first viable commercial substitute for silica-based column technology.
The XTerra Shield RP18 columns are made from highly pure methyl hybrid material. A procedure similar to that used to synthesize high-purity silica is employed to create this material, with one important difference: the XTerra substance is created by the combined condensation of two high purity monomers as opposed to only one. Tetraethoxysilane (TEOS) and methyltriethoxysilane are used to create the XTerra Shield RP18 columns during the hybrid particle synthesis process (MTEOS).
