The prepared video tutorials are about validation parameters of analytical methods as per ICH guidelines. These tutorials incorporate detailed insight of the ICH guidelines associated with validation of analytical methods. One of these guidelines is Q2A which defines the various terminologies used in analytical method validation while another one Q2B explains all these validation parameters in details. These tutorials were divided into two parts, This is Part-I which includes basic introduction of analytical method validation and explanation of first two parameters of method validation which are specificity and linearity while second part of this tutorial includes range, accuracy, precision, LOD, LOQ, robustness and system suitability criteria. For watching the second part please on this link • ICH Guidelines Part-II... . Thanks
