Bond Elut™ online SPE cartridges are designed for use with liquid chromatography (LC) to provide sample cleanup, and in certain applications, pre-concentration.

• Polymeric reversed-phase sorbent that is hydrophobic, with no bonded phase or alkyl ligands
• A flexible sorbent to use as a starting point for online SPE applications
• Suitable for applications with target compounds over a wide range of chemical properties
• Designed for use with the ZORBAX guard column hardware kit
• Very stable sorbent bed to support flow reversal
• PLRP-S pore size: 15 µm

Available with PLRP-s polymeric sorbent materials, the Bond Elut online SPE cartridges provide good stability and performance. Online SPE typically involves loading the sample onto the online SPE cartridge by applying flow in one direction across the sorbent, followed by a reversal of flow across the sorbent to elute the target analytes directly onto the analytical LC column. Coupled with mass spectrometry for detection, Bond Elut online SPE cartridges provide a simple, automated method for sample analysis and are ideal for use in the LC/MS/MS analysis of water for environmental contaminants.
