I know that TLC is better than melting point in terms of purity but I don't know how it's tested can someone help me?
how is purity of TLC tested in industry?

TLC:
You can use a reference spot of aspirin that is known to be pure, and run your product against it. If your product and the pure aspirin appear at the same Rf value with no extra or missing traces, you know that your product is pure.
Melting point:
More pure samples melt over a smaller temperature range. And assuming your melting point is in the expected range for the compound, generally a higher melting point indicates higher purity (for a confusing explanation of this, look up eutectics).
