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 contamination of the analytical column.
A retention gap helps focus compounds transferred from the inlet as a small band at the head of the analytical column, minimizing chromatographic peak broadening.

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

For connection guidance between an MXT guard column or retention gap (deactivated tubing) and an analytical column, refer to the MXT Low Dead Volume Connectors for Use with Fused Silica Capillary Columns installation instructions.
