C4 (USP L26) – Optimized for Large Biomolecules
C4 (Butylsilane) is a short-chain reversed-phase column designed for large biomolecules like proteins and peptides. It offers reduced hydrophobic retention, making it ideal for highly hydrophobic proteins and lipid-soluble compounds.
✔ Optimized for Large Molecules – Prevents protein denaturation.
✔ Lower Retention for Hydrophobic Compounds – Faster elution times.
✔ Better Peak Shape for Biomolecules – Minimal secondary interactions.
✔ USP Compliant – Suitable for biopharma quality control.
