thin-layer chromatographic adj

* * *

(TLC) chromatography in which the stationary phase is a thin layer of an adsorbent, e.g., silica gel, coated on a rectangular plate and the mobile phase is a solvent mixture. The sample is applied to a small spot on the plate, and then the plate is stood on end with its lower edge in solvent. As the solvent rises by capillary action through the adsorbent, the components of the sample are carried along at different rates and can be visualized as a row of spots after the plate is dried and stained or viewed under ultraviolet light.
