 - EC HPLC column (analytical), NUCLEODUR Sphinx RP, 5 µm, 250x2 mm
 
The mythical creature "Sphinx" has a lion body and often a human head. High purity NUCLEODUR silica gel is modified with a balanced ratio of propylphenyl and C18 ligands. This bifunctional RP phase shows a unique selectivity and widens the scope for method development based on hydrophobic and additional π-π interactions.
