- Made from highly pure (>99.995%) porous silica microspheres (pore size is the space between the solid silica microparticles)
- Stronger than other silica types
- Less acidic than ZORBAX-SIL, lower metal content
- Low acidity and low metal content make ZORBAX Rx-SIL ideal for normal-phase separation of polar compounds that exhibit poor peak symmetry on more acidic silica
- Useful for very hydrophilic compounds with high organic mobile phases in HILIC mode
*These columns ship containing reversed phase solvents. Flush with isopropanol before using normal phase solvents.
