Silica Columns

 

When silica is used as the stationary phase, the functional groups involved in separation are the surface silanols.  However, metal impurities in silica may provide additional sites of interaction for solutes of interest.  SMT uses high purity silica packing materials that are available in variety of particle and pore sizes.  These columns have performed well in the separation of many polar compounds such as pesticides and organic acids.

 

Unique features:

  Offers preferential retention of aromatic compounds.

  Complimentary to other reversed-phase materials such as C18, C8, and C4.
