SiliaChrom® Preparative HPLC Columns SB C18

The SiliaChrom SB C8 and C18 are specially designed for the separation of polar and mid-polar compounds from low to medium pH. A class of columns offering excellent performance for LC-MS applications. More Information

The surface of SiliaChrom SB C8 and C18 are treated with an organic form of silicon to increase the number of silanol groups on the surface. After this, the surface is bonded with an octadecylsilane with two different fonctions. One of them is a protecting group that shields the area under it and protects the surface from an acid attack from the mobile phase.

• 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)
