Agilent has enriched its catalog with ZORBAX Eclipse Plus columns, which provide excellent peak shapes for bases, acids, and neutrals. These columns offer new options for fast and ultra-fast HPLC, optimize the separation of analytes, and help overcome measurement challenges. The recently added Phényle Hexyle phase and C18 phase are designed for the separation of complex bases, acids, polynuclear aromatic hydrocarbons (PAHs), and environmental analytes. The ZORBAX Eclipse Plus columns ensure reproducibility and high-quality results for drug metabolism studies and pesticide analysis.
