Description

Guard columns and retention gaps are widely used in gas chromatography for different reasons.
A guard column traps nonvolatile material at the head of the column, preventing it from reaching and damaging the analytical column.
A retention gap helps focus compounds transferred from the inlet as a narrow band at the head of the analytical column, minimizing peak broadening.

Siltek-treated, stainless-steel MXT guard columns provide excellent compatibility with MXT analytical columns, combining the strength of metal with the inertness of glass. These guard columns can also function as retention gaps.

To learn how to connect an MXT guard column or retention gap (deactivated tubing) to an analytical column using an MXT low dead-volume connector, refer to the MXT Low Dead Volume Connectors for Use with Fused Silica Capillary Columns installation instructions.
