ReproSil 70 C8

Small-Pore C8 Column for Fast and Balanced Small-Molecule Separations

ReproSil 70 C8 from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 70 Å pore size and an octyl bonded phase. Offering moderate hydrophobic retention, this phase provides faster elution than C18 while maintaining excellent resolution and reproducibility for small-molecule applications. The small pore size ensures a high surface area, resulting in sharp peak shapes, high efficiency, and suitability for routine analytical methods in various industries.
