ACQUITY UPLC CSH Fluoro-Phenyl Column, 130Å, 1.7 µm, 2.1 mm X 50 mm, 1/pk
With an intricate combination of multiple retention mechanisms, the ACQUITY UPLC CSH Fluoro-Phenyl Column provides exceptional selectivity for positional isomers, halogenated compounds, and polar compounds. These retention mechanisms include dipole-dipole, hydrogen-bonding, aromatic (pi-pi), and hydrophobic interactions. Compared to the lab equipment used with traditional PFP-bonded stationary phases, the unique surface chemistry of the Charged Surface Hybrid (CSH) particle provides enhanced retention of acidic compounds.
CSH Technology is Waters’ third-generation hybrid particle technology, based on Ethylene Bridged Hybrid particle technology (BEH) and incorporating a low-level surface charge designed to improve sample loadability and peak asymmetry in low-ionic-strength mobile phases. This is achieved while maintaining the mechanical and chemical stability inherent in the BEH particle technology. This allows ACQUITY UPLC CSH Fluoro-Phenyl Columns to offer superior peak shape for basic compounds, increased loading capacity, rapid column equilibration, improved reproducibility, and exceptional stability at both low and high pH.
All ACQUITY UPLC CSH packing materials are designed for use with the ACQUITY UPLC systems and are manufactured in cGMP, ISO 9001 certified manufacturing facilities with the use of ultrapure reagents. Each batch of material is chromatographically tested with acidic, basic, and neutral analytes, and results are held to narrow specification ranges, allowing Waters to ensure excellent and reproducible performance. Further testing can be performed using Neutrals QC Reference Material.
This column is sold one per package with an inner diameter of 2.1 mm and a length of 50 mm and includes eCord Intelligent Chip technology for tracking the column’s performance history. All columns are shipped in 100% acetonitrile.
What Are Some Use Cases For ACQUITY UPLC CSH Fluoro-Phenyl Columns?
One of the most frequently prescribed medications in modern medicine, antibiotics are used to treat bacterial infections by inhibiting cell-wall synthesis of bacterial organisms. These columns successfully retain and separate Beta-lactam antibiotics in a rapid analysis time. Paroxetine is a selective serotonin reuptake inhibitor (SSRI) antidepressant that affects chemicals in the brain that may become imbalanced. This can be used to treat depression, obsessive-compulsive disorder, anxiety, and other mood disorders. The unique selectivity of ACUITY UPLC CSH Fluoro-Phenyl columns allows for successful resolution of cis- and trans- isomers of paroxetine.
