In paper chromatography, the solvent is usually allowed to move up the paper by diffusion, which can be slower and less controlled than TLC.

Additionally, TLC is often used for qualitative analysis, where the spots on the TLC plate are visualized and compared to known standards. In contrast, paper chromatography is commonly used for quantitative analysis, where the distance traveled by the compounds on the paper is measured and compared to a calibration curve.

In conclusion, both TLC and paper chromatography are valuable techniques for separating and identifying compounds in a mixture. While TLC offers better resolution and faster separation, paper chromatography is more cost-effective and simpler to perform. The choice between the two techniques depends on the specific requirements of the analysis.
