More recently, new information has been published, updating the previous guidelines and providing more detail and harmonization with International Conference on Harmonization (ICH) guidelines (5,6).The overall validation process begins with validated software and a validated (qualified) system; then a method is developed and validated using the qualified system.However, in some cases, it may be appropriate to perform or combine a given activity with another phase, Activities spanning more than one phase are indicated (*)After an IQ and an OQ have been performed, PQ testing is conducted.PQ testing should be performed under the actual running conditions across the anticipated working range.Since the late 1980s, government and other agencies (for example, FDA, International Conference on Harmonization-ICH) have issued guidelines on validating methods.

"The process of providing documented evidence that something does what it is intended to do." Validation is also the foundation of quality in the chromatographic laboratory, and AMV is just one part of a regulatory quality system that incorporates both quality control and quality assurance (1,2).First, fixed parameters, for example, length, weight, height, voltage inputs, pressures, and so forth are either verified or measured against vendor-supplied specifications.
