Reprospher 100 C18

Classical Reversed-Phase Column for Reliable and Reproducible HPLC

Reprospher 100 C18 is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, packed with high-purity, fully porous silica featuring a 100 Å pore size and bonded with octadecyl ligands. This well-established phase provides strong hydrophobic retention, excellent peak symmetry, and high column efficiency — making it a robust solution for a broad range of reversed-phase applications. With particle sizes from 1.7 µm to 10 µm and stable performance under acidic to neutral pH, this phase is ideal for pharmaceutical quality control, routine analysis, and method development.

Reprospher 100 C18 from Dr. Maisch HPLC GmbH offers dependable reversed-phase performance – a solid choice for high-resolution separations with classical C18 selectivity.
