SIELC Guard Columns for Chromatography
To ensure the longevity and consistent performance of analytical columns, the use of a guard column is highly recommended. Guard columns act as protective filters, capturing particulate matter and strongly retained contaminants before they reach the main column. The SIELC guard column features a uniquely designed direct-insert format that does not require any additional holders and provides zero dead volume connections to the analytical column. Guards are available for all SIELC packing materials, with a packing bed length of 10 mm, ensuring full compatibility and no change in selectivity. Designed to preserve the integrity of the separation process, SIELC guard columns extend the lifetime of the main column while maintaining high efficiency and reproducibility. Manufactured and quality-controlled in the USA, SIELC guard columns are an essential component of reliable and cost-effective chromatography workflows.
