Platinum is a premium column series designed for demanding reversed-phase HPLC applications requiring maximum resolution, reproducibility, and robustness. Based on ultra-high-purity, fully porous silica and bonded with optimized C18 surface chemistries, Platinum columns deliver outstanding peak symmetry, excellent batch-to-batch consistency, and superior performance across a wide pH range.
Thanks to a tightly controlled manufacturing process, the Platinum series is ideal for regulated pharmaceutical analysis, method validation, and challenging separations of closely related compounds.
Platinum columns offer top-tier performance and reliability – the ideal solution for laboratories with the highest chromatographic requirements.
The product line was aquired by Dr. Maisch HPLC GmbH in 2016 from Grace / Alltech.
