XTerra 2-methyl-2-phenylethyl Column, 125Å, 3.5 µm, 4.6 mm X 150 mm, 1/pk
The XTerra 2-methyl-2-phenylethyl Column composition consists of difunctional bonding chemistry of the short-chain phenyl ligand that imparts improved low pH hydrolytic stability. Using the unique combination of substrate and ligands, the XTerra 2-methyl-2-phenylethyl Column will enable you to have a new additional dimension in selectivity for separations of complex mixtures in your analysis.
The XTerra Phenyl columns are designed to offer chromatographers complementary selectivity in contrast to other straight-chain alkyl phases; this feature is specifically relevant for compounds that contain aromatic rings. The combination of Hybrid Particle Technology and the XTerra Phenyl chemistry yields a high pH stability stationary phase that has an excellent peak shape for all compounds and highly reproducible retention times. With the addition of the XTerra 2-methyl-2-phenylethyl Column to your lab, you will be able to attain the benefit from all these unique combinations and exceptional qualities of the analytical column and its chemistry.
The packing materials are synthesized using Waters Hybrid Particle Technology. The XTerra particles contain both inorganic (silica) and organic (organosiloxane) components, combining the advantages of both for high efficiency of separation and improved pH stability.
The manufacturing process of the XTerra 2-methyl-2-phenylethyl Column starts with ultrapure reagents to control the chemical composition and purity of the Hybrid particle. Every step of the process is conducted within narrow tolerances, under the strictest conditions and monitoring, to ensure the column you receive gives you the best possible results. Each column in the series is individually tested, and Waters provides Certificates of Batch Analysis and Column Efficiency with each column.

You may also be interested in theXTerra 2-methyl-2-phenylethyl VanGuard Cartridge, 125Å, 3.5 µm, 3.9 mm X 5 mm, 3/pk, which is recommended by Waters for use with the analytical XTerra Column as is designed to protect the XTerra 2-methyl-2-phenylethyl Column while enhancing its lifetime and performance by removing contaminants from the mobile phase stream.
What pH Range Can The XTerra 2-methyl-2-phenylethyl Column Operate Within?
The XTerra brand has multiple variations. However, the variations offer distinct advantages over their silica counterparts in terms of the wide-scale pH range. The MS columns offer stable chemical analysis between pH range (1-12) while the RP columns’ pH range is 2-12. The XTerra 2-methyl-2phenylethyl Column has an operating pH range of 1-12. Even though the columns are designed to have greater lifespans, they are still finite, and buffers will be a determining factor in the lifetimes.
