ReproSil-XR 120 C8 from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 120 Å pore size and an octyl bonded phase. The medium alkyl chain provides moderate hydrophobic retention, allowing faster elution than C18 while maintaining excellent resolution and reproducibility. This column is particularly suited for method development and routine analyses where balanced retention and shorter run times are desired, making it widely applicable in pharmaceutical, environmental, and food testing.
ReproSil-XR 120 C8 columns from Dr. Maisch HPLC GmbH combine balanced retention with high separation efficiency – the versatile choice for fast, reproducible reversed-phase HPLC separations.
