Area of Science:

  • Analytical Chemistry
  • Chromatographic Techniques

Context:

  • Thin Layer Chromatography (TLC) relies heavily on solvent system optimization for effective component separation.
  • Existing optimization methods often lack universality and are limited to samples with known components.

Purpose:

  • To develop and validate a complex, universally applicable method for optimizing TLC solvent systems.
  • To enhance the precision and efficiency of solvent system selection for complex samples.

Summary:

  • A novel complex method employing uniform design for experiment arrangement and regression analysis for solvent system optimization in TLC is presented.
  • The method involves determining solvent system complexity, arranging experiments via uniform design, and obtaining a regression equation from scanning chromatogram data.
  • Optimized solvent systems were determined for cortical hormone, sulfa drugs, and ginkgo biloba, with verification experiments confirming the calculated results.
