Nettet30. jul. 2024 · And How Does a TLC Work? Well, a TLC plate is an aluminum plate coated by a “thin layer” of a stationary phase, which is usually (>95% of the time in organic synthesis) silica gel. Around 1 cm above the bottom of the plate, you can spot a solution of a mixture of compounds of different polarity. Nettet26. feb. 2024 · How does thin layer chromatography work? The stationary phase - silica gel Silica gel is a form of silicon dioxide (silica). The silicon atoms are joined via oxygen atoms in a giant covalent structure. However, at the surface of the silica gel, the silicon atoms are attached to -OH groups.
