The KNAUER Sepapure® oliGO 120-3 is a high-performance HPLC/UHPLC column optimized for oligonucleotide analysis in both reversed-phase (RP) and ion-pair reversed-phase (IP-RP) modes.
The column is based on hybrid silica with advanced endcapping and hydrophobic modification, ensuring stable interactions, high reproducibility, and long lifetime, even under demanding conditions.
With 3 µm particles, the column delivers UHPLC performance while maintaining low back pressure, allowing use even on standard HPLC systems.
It is ideal for:
- identification
- quantification
- quality control (QC)
of oligonucleotides.
