ReproSil Star 100 C8 is a high-purity silica-based HPLC column with a C8 bonded phase, developed for demanding pharmaceutical and biotechnical separations. The shorter alkyl chains of the C8 modification provide moderate hydrophobic retention and faster elution compared to C18 phases, making this column ideal for analytes with medium polarity or for methods requiring reduced run times.
The specially treated ReproSil Star silica ensures high mechanical and chemical stability, sharp peak shapes, and reproducible retention even under challenging gradient or temperature conditions. This phase is particularly suitable for routine pharmaceutical analysis, impurity profiling, and biotechnical applications involving peptides and biomolecules.
ReproSil Star 100 C8 combines optimized silica performance with controlled hydrophobicity – the dependable choice for efficient pharmaceutical and biotechnical HPLC separations.
