How does thin layer chromatography help in identifying compounds?

Some points on thin layer chromatography in identifying compounds:

• Thin layer chromatography identifies compounds by comparing the position and pattern of sample spots with known reference standards. 
• After development, the sample and standard are visualized under suitable conditions such as ultraviolet light or chemical staining to make their spots clearly visible. 
• When the sample spot appears at the same relative position and shows a similar appearance as the reference spot, the compound is considered to be the same substance. 
• This comparison method allows unknown components in a mixture to be recognized without requiring complex instrumentation or advanced analytical techniques.
