NUCLEODUR® C18 PolarTec is an octadecyl modified silica phase with embedded polar group for HPLC.

• High purity spherical silica gel
• Hydrophobic, polar and steric RP phase with high stability in 100% aqueous eluents
• Separation mechanism based on hydrophobic, polar and steric interactions

The LC-MS suitable phase NUCLEODUR® PolarTec has an exceptional selectivity for phenols and nitrogen containing compounds. Further polar compounds like organic acids, amino acids, water soluble vitamins, pesticides, and basic pharmaceuticals can be well seperated.
