Description
The ASTRA brand extends new line of the ARION® HPLC columns. What new bring this column to you?
- Strict quality control of alkaline and heave metals content during silica gel production process (<10 ppm)
- Narrow particle size and pore volume/size distribution
- Unique production process ensuring high lot-to-lot reproducibility
- High end-capping in gaseous phase
| Main particle characteristics: |
|---|
- High proximity to the circle
- Surface smoothness
- Tight particle size distribution
- No broken particles
- No presence of clustered particles
- No “Moon craters or mountains”
Aplications on Astra® HPLC columns are available at ARIONCHROMATOGRAPHY
