Adsorbosil C8 is a reliable reversed-phase HPLC column based on fully porous, high-purity silica modified with octyl (C8) groups. Offering medium hydrophobicity, it provides shorter retention times compared to C18 while maintaining good selectivity and peak shape.
This makes Adsorbosil C8 especially suitable for analytes that elute too slowly on C18 phases or when faster run times are desired without compromising separation quality. It is widely used in pharmaceutical, environmental, and food analysis workflows.
Adsorbosil C8 offers an excellent alternative to C18 columns for medium-polarity compounds, delivering faster analysis and reproducible performance.
Adsorbosil C8 is a good alternative to Polygosil® C8.
