Adsorbosphere C18

Classic Reversed-Phase Column for Reliable HPLC Performance

Adsorbosphere C18 is a fully endcapped octadecyl-modified (C18) HPLC column based on high-purity, fully porous silica. It is engineered for reproducible reversed-phase separations of hydrophobic and moderately polar compounds, making it an excellent all-purpose column for routine analysis and method development.

With strong retention characteristics, low silanol activity, and good peak symmetry, Adsorbosphere C18 is ideal for both isocratic and gradient elution. Its chemical stability and consistent performance make it particularly suitable for pharmaceutical, food, and environmental applications.

Adsorbosphere C18 offers classic reversed-phase selectivity with high reliability – making it a solid choice for everyday HPLC tasks in regulated and non-regulated environments.
