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.
- Wide pH range
- High Carbon loading
- Very stable for agressive mobile phases
- Accepts large injection volume (50 µL and more)
- Double endcapped

SiliaChrom® XDB1 CN is a versatile stationary phase which can be used in normal phase or reverse phase conditions. This stationary phase is ideal for basic pharmaceuticals, steroids and other basic compounds.
SiliaChrom® XDB1 NH2 is a very versatile stationary phase which can be used in normal phase, reverse phase or ion exchange conditions as a weak anionic exchanger (WAX).
SiliaChrom® XDB1 Si is ideal for normal phase applications. This spherical silica support is characterized by its very high level of purity (99.999 %).
