Advantages:
1. Simplicity:
Paper chromatography requires minimal equipment and is easy to set up.
2. Low Cost:
Relatively inexpensive compared to techniques like HPLC or GC.
3. Versatility:
Can be used to separate a variety of polar and non-polar compounds.
4. Qualitative and Semi-quantitative Analysis:
Useful for identification and comparative analysis.
Disadvantages:
1. Resolution:
Limited resolution compared to more advanced chromatographic techniques.
2. Sensitivity:
Not as sensitive as techniques like HPLC or GC; might miss trace components.
3. Quantification:
Quantitative analysis is less precise compared to other methods.
4. One-time Use:
Each paper can only be used once.
Applications:
1. Education:
Commonly used in teaching labs because of its simplicity and visualization capabilities.
2. Food Industry:
Used to detect and separate food additives, colors, and flavors.
3. Pharmaceuticals:
