NUCLEODUR® C18 Isis is a specially crosslinked octadecyl modified silica phase for HPLC with multi-endcapping.
- High purity spherical silica gel
- Hydrophobic, weakly polar RP phase with an exceptional steric selectivity
- Separation mechanism based on hydrophobic and steric interactions
With its steric selectivity the phase is successfully applied for separations of steroids, (o,p,m-) substituted aromatics, and fat-soluble vitamins. It is suitable for LC-MS application due to a low bleeding characteristic.
