When it comes to sample cleanup the question occasionally comes up asking what technique is best for my application? Solid Phase Extraction (SPE) or Supported Liquid Extraction (SLE). Well, what’s right for you depends on your application and the characteristics of your analytes. Both techniques offer high recoveries, are reproducible, and are easily automated. In this post I would like to outline some of the advantages, disadvantages and limitations of each technique.
