To ascertain the degree to which an analytical method is deemed suitable for its intended use, the validation parameters set forth in ICH Q2(R1) Validation of Analytical Procedures (6) stipulates the following criteria: Not all parameters can be evaluated because a reference standard is required to perform quantitation. While USPs public health mission has remained unchanged for over 200 years, the global healthcare landscape has been anything but static. Both the core name (ex. For information relating to LGCs data processing activities, please visit our Privacy Policy below (see footer). If the reference standard is in a salt form, the amount of salt present must be determined so that the purity can be corrected for content. It is important, therefore, to consider how the material will be stored, distributed, and controlled. Compounds that are susceptible to hydrolysis, for example, should be thoroughly dried to remove moisture and then stored in a desiccator.

Please make sure there are no leading or trailing spaces as this will not return correct results. Thus, it is unnecessary to name repetitively the revised Reference Standards in the general index to the Supplement. Inorganic impurities such as metals and noncombustible materials are typically evaluated using compendial procedures. Javascript is currently disabled in your browser. For further information on this product, please consult its ATCC.org product page under General Information, Permits and Restrictions and BSL. The total length of the requalification program will depend on the intended life of the reference standard and the length of the stability and clinical programs. More analytical tests must be performed, and the probability of the purity changing during the review period increases.
