Methodological validation






Given the risks there might be to health from the intake of uncontrolled amounts of impurities in drugs, control protocols are continually being developed for established maximum intakes.

Currently being reviewed are the USP (United States Pharmacopeia) standards and European guidance ICH Q3D, which set limits allowed for both inorganic impurities in the active ingredients and the analytical methodologies used. These rules also state permitted daily exposure limits (PDE) for each of impurities.

Because of the need to meet regulatory requirements, it is a requirement to use in the analysis of these compounds techniques which are sensitive and validated in accordance with the requirements reflected in the USP 232, 233 USP and ICH Q3D guide standards. These standards require that the methods are able to analyze reliably impurities in the corresponding established limits, fulfilling criteria of Accuracy, Precision, Robustness, Specificity, Linearity and Detection Limit.


The need to meet regulatory requirements means customers must consider having validated methodologies, and setups that require the latest technology, which are not accessible to all laboratories.
