The Agilent ZORBAX RRHD Eclipse Plus C18 column is engineered for ultra-high-performance liquid chromatography (UHPLC) applications requiring fast, high-resolution separations of complex mixtures. With fully porous 1.8 µm silica particles, a 95 Å pore size, and a stable pressure rating up to 1200 bar, this column delivers exceptional efficiency and reproducibility across a wide range of workflows.
Its double endcapping technology improves peak shapes by minimizing secondary interactions, making it highly suitable for acidic, basic, and neutral compounds. Operating within a pH range of 2–9, the column is robust under demanding conditions, supporting maximum performance with compatibility for EPA Method 533.
