Solid Phase Extraction

   

Solid Phase Extraction products provide cost-effective, fast and efficient sample clean-up and concentration prior to analysis through gas chromatography (GC), high performance liquid chromatography (HPLC) and/or other analytical methods.


SPE cartridges are comprised of three main components:

  • Clean medical grade polypropylene tubes
  • Clean and porous polyethylene frits
  • High quality, reproducible sorbents and/or stationary phases.
Cerex Solid Phase Extraction Tubes
 

The cartridges are designed with both manual and automated uses in mind. All of our solid phase extraction syringe cartridges are equipped with male Luer-tips, providing great versatility for connections and processing.


Common processing methods include using a syringe plunger to introduce the sample/solvent into the syringe barrel, placing the SPE cartridge into a centrifuge and pulling the  sample/solvent through the cartridge by centrifugal force, or boring a hole in a rubber stopper to accommodate the SPE cartridge and placing the stopper in a vacuum flask. Vacuum aspiration is then used to pull the sample/solvent through the cartridge.


In a similar application, multiple cartridges may be used to process multiple samples by using an adapter and vacuum manifold hooked up to a vacuum source. Sample throughput may also be increased by using large-reservoir SPE cartridges. Combined with other automation methods, significant gains in lab efficiency may be achieved.

Crawford Scientific offer four options when it comes to choosing SPE products:
