Restek Capillary Guard Columns

The Restek Capillary Precolumns are a highly specialized option for gas chromatography, specifically designed for use in combination with capillary columns. These precolumns are manufactured by Restek and are used as a preliminary stage before the main column in chromatographic analysis.

The Restek capillary precolumns are designed to enhance the separation and performance of gas chromatography by removing unwanted compounds before they reach the main column. These precolumns typically have a shorter length and a smaller internal diameter compared to conventional capillary columns. This allows for greater separation efficiency and minimizes contamination of the main column, resulting in improved analytical results.
