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^® SB C18 has the particularity that the silane carries two different functions:

• The C18 Hydrophobic function

• Transversal hindered isopropyl groups which protect the surface from an acidic attack.

This chemistry guarantees the stability of this reverse phase in very low pH (up to 0.8)

SiliaChrom^® XDB C18 presents the same bonded phase as the SiliaChrom XDB 1 C18 and XDB1 C18-300. The pore size of the silica support is intermediate, 150 Å, which allows to separate larger molecules than its 100 Å equivalent. The lower surface associated allows compounds to have shorter retention times. SiliaChrom XDB C18 is an excellent equivalent to Hypersil BDS-C18 and Zorbax XDB-C18.

SiliaChrom^® XDB1 C18 column has the highest loading density available as well as the highest hydrophobicity. This allows it to have the least interactions between the analytes and potential residual silanol groups.

SiliaChrom^® XDB 1 C8 columns offer faster separations for strongly hydrophobic analytes compared to C18 columns. As the C18 XDB1 phase, the C8 XDB1 is highly base deactivated.

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 Phenyl can conjugate hydrophobic interactions and electronic π-π interactions with unsaturated compounds. This stationary phase is excellent for polynuclear aromatic hydrocarbons, purines and polar aromatics.

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 C4 presents a less hydrophobic character than C18 and C8 SiliaChrom XDB1 columns. This stationary phase is ideal for peptides and small proteins.

SiliaChrom^®XDB1 C1 is the least hydrophobic reverse phase available. This phase is useful for very high hydrophobic molecules.

SiliaChrom^® XDB2 C18 is grafted on ultrapure spherical silica whose surface was activated to create a high concentration of OH before grafting the C18 function. The residual carbon load is lower than the SiliaChrom XDB1 equivalent.

SiliaChrom^® dt C18 has the same unique technology phase as SiliaChrom AQ C18, but the purity of the spherical silica gel is 99,999%, the highest value for HPLC SiliaChrom Series. 

SiliaChrom^® XT C18 has a hybrid surface made from a condensation of inorganic SiO2 species and an organosilane (CH3-SiO1.5). This hybrid, a more hydrophobic matrix, presents a very high resistance to extreme high pH conditions (up to 12).

SiliaChrom^® XT Fidelity C18 has a hybrid surface composed from a condensation of inorganic SiO2 species and an organosilane (CH3-SiO1.5). This hybrid, a more hydrophobic matrix, has an incomparable resistance to extreme high pH conditions (up to 12). The only difference between SiliaChrom XT C18 and SiliaChrom XT Fidelity C18 is the way they are packed, giving Fidelity columns more robustness at high pH and temperature.

SiliaChrom^® C8 reverse phase functionalization is completely identical to the SB C8 equivalent. This reverse phase is grafted on a 300 Å pore size spherical silica to separate or purify larger molecules.

SiliaChrom^® XDB1 C18-300 reverse phase functionalization is completely identical to the XDB1 C18 equivalent. This reverse phase is grafted on a 300 Å pore size spherical silica to separate or purify larger molecules.

SiliaChrom^® XDB1 C8-300 reverse phase functionalization is completely identical to the XDB1 C8 equivalent. This reverse phase is grafted on a 300 Å pore size spherical silica to separate or purify larger molecules.

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 Phenyl-300 chromatography phase functionalization is completely identical to the XDB1 Phenyl equivalent. This reverse phase is grafted on a 300 Å pore size spherical silica to separate or purify larger molecules.

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 C4-300 reverse phase functionalization is completely identical to the XDB1 C4 equivalent. This reverse phase is grafted on a 300 Å pore size spherical silica to separate or purify larger molecules.
