AttractSPE™ - Polymeric SPE cartridges

Polymeric Solid Phase Extraction Sorbents

Sample preparation and clean-up are the key steps in trace analysis for every analytical chemist. Solid phase extraction (SPE) is a powerful technique providing a rapid and selective sample clean-up, a high analyte recovery and preconcentration necessary for an accurate quantitative analysis.

Thanks to its expertise in polymer chemistry, AFFINISEP has developed a complete range of polymeric SPE phases: AttractSPE™.

AttractSPE™ columns and 96-well Plates are sample preparation products making possible the extraction of compounds from complex matrices. AttractSPE™ sorbents support the six common retention mechanisms used in analytical laboratories:

 

Benefits

AttractSPE™ products provide all the advantages of polymeric sorbents, including robustness, simplified method development, wide applicability and are not affected by drying out. The combination of the water-wettable optimised surface chemistry, high surface area and pH stability ensures high reproducible recoveries for a wide range of analytes.

 

Determination of the optimal AttractSPE™ polymeric sorbent

Simply follow the method to choose the optimal AttractSPE™ polymeric phase for your analysis:

  1. Determine the nature of the target analyte: neutral, acidic or basic.
  2. Determine the pKa of the analyte.
  3. Using the following chart, choose the most appropriate AttractSPE™ phase.
