Application Benefits
- Quickly identify optimal chiral conditions
- Excellent method transfer from other platforms
- Enhanced column lifetime with correct handling
- Normal-phase workflows with minimal optimization
Column Operating Guidance
- Ensure system is free from water contamination before use
- Flush system (no column) with IPA→ mobile phase
- Dissolve samples in designated mobile phase
- Filter samples & mobile phases ≤0.5 μm
- Follow additive removal prior to storage
- Store columns capped in shipping solvent at room temperature
Operating in accordance with these procedures ensures maximum lifetime and performance.
