SiliaChrom® Narrow Bore 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® Narrow Bore 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® Narrow Bore 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® Narrow Bore 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® Narrow Bore HPLC Columns AQ C18
SiliaChrom® AQ C18 columns use a new generation adsorbent based on high purity spherical silica and unique bonding technology.
-
SiliaChrom® Narrow Bore 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® Analytical 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® Analytical HPLC Columns XDB C18
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® Analytical 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® Analytical 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® Analytical HPLC Columns XDB1 C18-300
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.
