Thin layer chromatography (TLC) is an extension of paper chromatography and uses a different stationary phase. 2.3A: Overview of TLC. Using thin layers of stationary phase for separations is called "thin layer chromatography" (TLC), and is procedurally performed much the same way as paper chromatography. 2.3B: Uses of TLC.

TLC plates are generally made of aluminum coated by the stationary phase, and can be cut with scissors. Sometimes, the supporting material is glass and you will need a glass cutter to do the job. Usually, a thin layer chromatography plate is around 5–7 cm high, and a line is drawn around 0.5–1.0 cm from the bottom.CHEMISTRY LAB. TOTAL SYNTHESIS.
