SiliaChrom®- XDB1 HPLC Columns (Normal Phases)
SiliaChrom XDB1 phases present a complete normal phases family HPLC columns (SiO2, Diol, CN, AMINO). These phases present the maximum bonding density. This allows least interaction between the analytes and the surface OH's.
SiliaChrom XDB1 CN: Maximum hydrophobicity and accepts normal and reversed conditions.
 |
 |
SiliaChrom XDB1 Si: Designed for normal phase conditions, presents high surface area and low metal content.
 |
|
SiliaChrom® XDB1 DIOL: Excellent for normal phase applications with more hydrophobic activity.
 |
|
SiliaChrom XDB1 AMINO: Superior general purpose amino phase, recommanded for normal phase analysis and excellent for sugar analysis.
Main Characteristics
- Wide pH range
- High Carbon loading
- Very stable for agressive mobile phases
- Accepts large injection volume (50 µL and more)
- Double endcapped
