The KNAUER AZURA HTQC UHPLC (1240 bar) is a high-performance UHPLC system designed for high-throughput quality control (QC) where speed, robustness, and reproducibility are essential.
The system features a unique concept of parallel analysis and offline column re-equilibration, significantly increasing productivity. With two gradient pumps, one column performs the analytical run while the second is re-equilibrated in backflush mode.
This architecture enables:
- ≥30% reduction in cycle time
- increased sample throughput
- column protection from matrix contamination
- consistent retention times
It is ideal for pharmaceutical QC laboratories requiring automation and validated workflows.
