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® 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.
