ReproSil-XR is a high-resolution HPLC column series from Dr. Maisch HPLC GmbH, designed for applications requiring extended retention, maximum resolution, and superior peak capacity. Built on ultra-pure, fully porous silica with optimized pore and particle structures, ReproSil-XR columns are available in C18 and other reversed-phase selectivities to accommodate a broad range of analytical challenges.
These columns are ideal for complex mixtures, closely eluting analytes, and impurity profiling, especially in pharmaceutical, chemical, and environmental laboratories where separation power and reproducibility are critical.
ReproSil-XR columns from Dr. Maisch HPLC GmbH deliver extended retention and exceptional resolution – the ideal solution for high-performance analytical HPLC requiring maximum separation power.
