XTerra Shield RP18 Prep Column, 125Å, 5 µm, 7.8 mm X 150 mm, 1/pk
To rapidly and effectively improve peak shape performance for highly basic compounds, invest in the Xterra Shield RP18 Column. The laboratory makes use of a general-purpose, hybrid-based, reversed-phase C18 column with incorporated polar group technology that is patented by Waters. The XTerra Shield RP18 column is a first-generation column that offers improved pH stability when compared to a silica-based column.
Overcome the significant drawbacks of silica-based reversed-phase packing materials, particularly their hydrolytic instability at high pH, by using the XTerra Shield RP18 Column. The lab equipment uses Waters' distinctive organic/inorganic Hybrid Particle Technology (HPT), which enables it to provide a number of benefits above conventional silica columns. The first commercially viable silica-based column substitute is the Waters XTerra line of reversed-phase HPLC columns.
One significant distinction between the production of high-purity silica and the high-purity methyl hybrid material used in the XTerra Shield RP18 Column is that the XTerra material is created by the combined condensation of two high-purity monomers as opposed to one. The XTerra Shield RP18 Column's Hybrid Particle Synthesis is carried out using TEOS and MTEOS. The XTerra Shield RP18 Column, like other lab equipment made by Waters, is produced under ISO 9001 guidelines, guaranteeing that every step is carried out to the highest standards and tightest tolerances.
Comparing the Waters XTerra Shield RP18 to currently available standard silica columns reveals a number of noteworthy benefits. Among them are pore size tailoring, purity, pore dimensions, surface area, mechanical strength, highly spherical shape, and surface chemistry. The lab equipment does this by using conventional bonding agents. Additionally, it enables the XTerra Shield RP18 column, a crucial piece of all-purpose laboratory equipment, to maintain high separation efficiency, improve pH stability, and achieve optimal shape performance for highly basic chemicals.
