Analytical HPLC columns, ultra C4 (USP L26)
: Restek
Ultra C4 columns made of high-purity, type-B silica are designed for selective and reliable HPLC applications.
- Exceptionally stable C4 packaging
- High bonding coverage and base deactivation
- Less retention than C18 or C8 phases
- Minimises activity and creates high-density bonding
- Catalog No:
