Various advantages of HPTLC over HPLC

Both HPTLC and HPLC are well-recognized for the separation of analytes and for qualitative and quantitative analysis and they have many advantages.
Here are some of the advantages of HPTLC on HPLC as follows: 

• Preparation of the sample is simple.
• Maintenance costs are low. 
• The whole spectrum can be seen. 
• Many analysts can work together on the same system. 
• Consumption of solvents per sample is very low. 
• Solvents do not need any prior treatment, such as filtration and degassing. 
• There is no need to clean the sample. 
• There is no effect of the turbid sample on analysis. 
• Using the freshly prepared mobile phase, there is no chance of interference from the previous analysis.
• Analytical grade solvents are suitable. There is no need for expensive solvents. 
• UV absorption and Corrosive mobile phase can also be used. 
• High flexibility in the different steps, such as the selection of mobile phase, stationary phase, and developing techniques. 
• More basic pH can be used in a mobile phase, which is not suitable in HPLC. 
• An analytical requirement is least. 
• Technically simple, no skilled person is required to learn and operate. 
• Precoated HPTLC plates are available in low cost. 
• The solution of the solvent is not extremely significant for sample solubility because it is completely removed prior to developing chromatogram. 
• Sampling and standard can be processed simultaneously under the same condition provide better analytical accuracy and precision.
