Guard Columns

Consistent Resolution in RP Chromatography

It makes sense to ensure consistent resolution in reverse-phase (RP) chromatography by removing non-polar contaminants, particularly in diagnostics applications and food analysis. With our large selection of stainless steel guard columns and stationary phases, we can meet your needs for HPLC hardware and consumables.

Whenever consistent resolution and reproducibility are required, e.g. in samples from biological matrices, our customers can select from a wide variety of bonded solid phases. From food analysis to forensic toxicology, the routine for every chromatographic method is to use column guards to protect your investment and to ensure consistent operations at only a fraction of the cost for a new HPLC or UHPLC column.

When using HPLC guard columns to protect the columns, a column holder is required. The following diagrams show you the connection possibilities when you need a precolumn to an HPLC column (column connectors have to be ordered separately):
