The technique of pseudophase liquid chromatography is described. In this type of separation, a substance does not partition to the bulk mobile phase but rather to discreet aggregates or other substances (i.e., micelles or cyclodextrins) which are dissolved in the mobile phase. Advantages of this technique include high selectivity, low cost, and low volatility and toxicity of the mobile phase. Appropriate previous TLC separations are reviewed and new data on the separation of quinones are presented.
