SiliaChrom® Preparative HPLC Columns XT C18
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® Preparative HPLC Columns HILIC
SiliaChrom® HILIC (Hydrophilic Interaction Chromatography) HPLC columns are designed to retain highly polar analytes. SiliaChrom HILIC has a selectivity that is complementary to the one of reversed-phase columns. In fact, it has a higher retention for hydrophilic compounds in HILIC mode. HILIC sorbent is more stable and reproducible than normal phase silica or amino columns. This phase is ideal for MedChem laboratories and approved for SFC applications.
-
SiliaChrom® Preparative HPLC Columns AQ C8
SiliaChrom® AQ C8 columns use a new generation adsorbent based on high purity spherical silica and unique bonding technology.
-
SiliaChrom® Preparative HPLC Columns AQ C18
SiliaChrom® AQ C18 columns use a new generation adsorbent based on high purity spherical silica and unique bonding technology.
-
SiliaChrom® Preparative HPLC Columns dt C18
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® Preparative HPLC Columns XDB2 C18
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® Preparative HPLC Columns XDB1 CN
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® Preparative HPLC Columns SB C18
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® Preparative HPLC Columns XDB1 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® Preparative HPLC Columns SB C8
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® Preparative HPLC Columns XDB1 C8
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® Preparative HPLC Columns dt Si
SiliaChrom® dt Si has the same unique technology phase as SiliaChrom AQ Si, but the purity of the spherical silica gel is 99,999%, the highest value for HPLC SiliaChrom Series. This phase has no metal content, in order to avoid secondary interaction with basic or ion species.
-
SiliaChrom® Preparative HPLC Columns XDB1 AMINO
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® Preparative HPLC Columns XDB1 Si
SiliaChrom® XDB1 Si is ideal for normal phase applications. This spherical silica support is characterized by its very high level of purity (99.999 %).
-
SiliaChrom® Preparative HPLC Columns XT C18 Fidelity
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® Preparative HPLC Columns RPC-H
This polymer based stationary phase presents a high C18 substitution. You will enjoy it in extreme pH conditions for your reverse phase applications.
