Method validation is a systematic and well-defined process of demonstrating or confirming the performance characteristics of an analytical method. The key performance characteristics are accuracy and precision. Simply put, validation is demonstrating that the method is suitable for its intended purpose - a requirement of the current GMPs.

Nobody has more experience in method validation for dietary supplements than TBAR.  Dr. Roman is author and instructor of several validation training courses, and is author or co-author on many published validation manuscripts, including ephedrine alkaloids (which is now the AOAC official method of analysis), biogenic amines in Citrus aurantium, chondroitin sulfate, coenzyme Q10, and others.

TBAR follows AOAC guidelines for single laboratory validations, which are the most rigorous and statistically based validation protocols of any organization. 

If you would like to take your method to the next level of validation, Dr. Roman also has extensive experience designing and directing multi-laboratory collaborative studies, and is author and instructor for the AOAC training course on design and management of collaborative studies.
