Dionex™ SolEx™ HRP columns provide fast, easy sample preconcentration of contaminants in water by solid-phase extraction (SPE) prior to HPLC analysis.

• Higher retention properties in both polar and hydrophobic analytes
• No de-wetting, even with 100% aqueous phase
• High capacity with good recoveries
• Wide pH compatibility (0 to 14)
• Wide range of compounds—from polar to hydrophobic analytes

Packed with a hydrophilic reversed phased (HRP) resin comprising divinylbenzene polymer with a hydrophilic bonded layer these columns are placed in the valve to automatically concentrate the analytes of interest.
