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.

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® Amino chromatographic phase functionalization is completely identical to the XDB1 AMINO equivalent. This reverse phase is grafted on a 300 Å pore size spherical silica to separate or purify larger molecules.
SiliaChrom® XDB1 Si-300 is an ultrapure spherical silica support with a pore size of 300 Å. This spherical silica support is characterized by its very high level of purity (99.999 %).
SiliaChrom® XDB1 CN-300 chromatography phase functionalization is completely identical to the XDB1 CN equivalent. This reverse phase is grafted on a 300 Å pore size spherical silica to separate or purify larger molecules.
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 %).
