Why is thin layer chromatography considered a simple analytical method?

Some points on thin layer chromatography as a simple analytical method:

• Thin layer chromatography is considered simple because it requires minimal equipment, small sample quantities, and short analysis time. 
• The method uses only a coated plate, a suitable solvent system, and basic visualization tools, avoiding the need for complex or expensive instruments. 
• Since only microgram amounts of sample are applied, preparation is quick and waste of chemicals is very low. 
• The separation process is completed within a short period, making the technique suitable for rapid testing and routine laboratory work.
