Answer / avyaya prabhu
Method will be validated if it is newly developed.
Where as compendial method will be verified in a laboratory for suitability,to establish a documental evidence that the method is performing as intended.
Method validation will be conducted with all parameters like Specificity, Accuracy,Precision, Linearity, Robustness & LOD LOQ.
Where as method verification will be conducted with performance parameters only like Specificity, Accuracy, Precision and Robustness.

Method Validation: It is performed either when method is non-compendial or any changes has been made in a compendial method. only few parameters shall be validated if any changes has been in a compendial method.
Method verification: It is performed when method is compendial and only few parameters have to be checked as before implementing these method in a monograph, pharmacopoeia usually validate the method. only thing to be checked is the suitability of the method.
Thank you
