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.
Offers preferential retention of aromatic compounds.

SMT Silica – Normal Phase Silica Column
Silica Columns are used for further modification or separation of polar compounds. These normal phase columns contain high surface area and surface deactivation to which results in exceptional performance.
SMT SAM Silica – Guard Column
Silica Guard columns are expendable small columns designed to remove anything that may interfere with the separation or shorten the lifetime of the primary column.
