Method validation approaches for pharmaceutical assessments — highlights with high performance thin layer chromatographic (HPTLC) techniques

The high performance thin layer chromatographic (HPTLC) technique for analyzing pharmaceuticals can save resources, diminish testing time and reduce chemical waste, and its suitability for pharmaceutical testing is well documented. However, its implementation in developing countries has been slow. The authors provide information for the validation and thus application of HPTLC methods in resource-limited settings for pharmaceutical testing.
