Astra AQ HPLC column 5.0 µm 250 mm × 4.6 mm
HPLC column developed in the Czech Republic.
- Description
HPLC column developed in the Czech Republic. HPLC column particles are continuously analyzed by SEM.
The column is suitable for analytical separations.
Main particle characteristics:
- Close proximity to a sphere.
- Highly effective endcapping.
- No broken particles.
- Robustness to high pressures.
- Lot-to-lot reproducibility.
- Unique modern embedded phases.
Column hardware:
- Electropolished with very low Ra reduces wall effect.
