Abstract
Poor resolution and sensitivity are not inherent in thin layer chromatography (TLC). They merely re-flect the fact that TLC, as normally practiced, is not a high performance (efficient) technique. When efforts are made to improve the efficiency of TLC, the re-sulting improvements in resolution and sensitivity make high performance TLC fully comparable to high performance liquid chromatography (HPLC). Two approaches to improved TLC performance are the use of small-particle TLC plates and the technique of Programmed Multiple Development (PMD). Prelimi-nary PMD methods for limonin in citrus juice and for caffeine in cola beverages clearly illustrate the use of PMD.
