Some practical examples of method validation in the analytical laboratory
TrAC Trends in Analytical Chemistry, 1999
Method validation is a key element in both the elaboration of reference methods and the assessment of a laboratory's competence in producing reliable analytical data. Hence, the scope of the term method validation is wide, especially if one bears in mind that there is or at least should be a close relation between validation, calibration and quality control QA /QC. Moreover, validation should include more than the instrumental step only since the whole cycle from sampling to the ¢nal analytical result is important in the assessment of the validity of an analytical result. In this article validation is put in the context of the process of producing chemical information. Two cases are presented in more detail: the development of a European standard for chlorophenols and its validation by a full scale collaborative trial, and the intralaboratory validation of a method for ethylenethiourea using alternative analytical techniques.
Validation of analytical methods and laboratory procedures for chemical measurements
Arhiv za higijenu rada i toksikologiju, 1998
Method validation is a key element in the establishment of reference methods and in the assessment of a laboratory's competence in producing reliable analytical data. Hence, the scope of the term "method validation" is wide, especially if one bears in mind the role of Quality Assurance/Quality Control (QA/QC). The paper puts validation in the context of the process generating chemical information, introduces basic performance parameters included in the validation processes, and evaluates current approaches to the problem. Two cases are presented in more detail: the development of European standard for chlorophenols and its validation by a full scale collaborative trial and the intralaboratory validation of a method for ethylenethiourea by using alternative analytical techniques.

It is internationally recognized that validation is necessary in analytical laboratories. The use of validated methods is important for an analytical laboratory to show its qualification and competency. In this update on analytical quality, we place validation of analytical methodologies in the broader context of quality assurance (QA). We discuss different approaches to validation, giving attention to the different characteristics of method performance. We deal with the concepts of single-laboratory or in-house validation, inter-laboratory or collaborative study, standardization, internal quality control (IQC), proficiency testing (PT), accreditation and, finally, analytical QA (AQA).
An Overview of Analytical Method Validation
Universal Journal of Pharmaceutical Research, 2020
In line with the developments in the pharmaceutical field, the product range is constantly being renewed and diversified. New analytical techniques need to be developed and validated for new pharmaceutical products. The validation of an improved method is an internationally recognized scientific requirement, as these validation practices are also indicative of the competence of the analytical laboratory. The method development is a process that ensures the applicability and reliability of the data. The result is a more comprehensive understanding of the standard test methods and a further insight into the connection between test methodology and product quality. It is important to validate an advanced method. Because if the method can not be reproduced, the method is meaningless. Validation is a continuous balance among costs, risks and technical possibilities.

Approches of Analytical Method Development and Validation: A Review
International Journal of Research, 2021
The development and validation of analytical method requires estimation of active pharmaceutical ingredients (API), degraded products and selection of solvents for reducing the bias errors and significantly improve the precision. It plays a critical part in risk assessment and develops a precise way of acceptance criteria regarding drug consent by regulatory authorities. During drug development there is a demand for new sensitive and accurate method development procedure for rapid analysis by quality assurance as well as quality control department. Advanced analytical instruments reduced the cost, time of study and increase accuracy, precision. The most sensitive method for qualitative and quantitative estimation for drugs is spectroscopic and chromatographic techniques. It is involved in drug discovery, production and identification of toxicity and purity of drugs. The guidelines of ICH provide the validation parameters in terms of precision, linearity and accuracy, detection limit (LOD), limit of quantification (LOQ), suitability of system and robustness. The review focused on to explain systematic approaches to develop a sensitive, accurate and specific method for analysis pharmaceutical substances and pharmaceutical products.
A Recent Review On Analytical Method Development and Validation
Zenodo (CERN European Organization for Nuclear Research), 2022
In this review articles, the development, formulation, and manufacture of drugs, analytical method development & validation play a critical role. Methods are developed for ensuring purity, identity, potency, and performance of pharmaceutical products. Methods should be applied to the extent that they are sufficient for their intended purpose. Throughout the life cycle of a drug product and substance, a range of activities are associated with developing and validating methods. An objective of method validation is to prove that the procedure can be used as intended. Once the method is developed, validation is performed. Different national and international committees have defined the parameters for method validation. The International Conference on Harmonization attempted to harmonize pharmaceutical applications. In accordance with the ICH, other
Comparison of various international guidelines for analytical method validation
Pharmazie
Analytical method validation is the systematic process of establishing that an analytical method is acceptable for its intended purpose. In general the developer or user of the method generates evidence on specificity, linearity range, accuracy, precision, detection limit, quantitation limit, ruggedness and robustness of the method for regulatory submissions or in-house application. The iterative process of method development and validation has a direct impact on the quality of the above data. Such validated analytical methods for qualitative or quantitative testing of drug molecules assume greater importance when they are employed to generate quality and safety compliance data during development and post-approval of drug products. The present paper aims to discuss salient points of the analytical method development and validation cycle. It also attempts to compare and summarize guidelines issued by different agencies for validation of analytical methods used for analysis of drug su...
Evaluation and Application of Best Practice in Analytical Method Validation
Journal of Liquid Chromatography & Related Technologies, 2007
Method validation is an important part of analytical chemistry to confirm that the method employed for a specific test is suitable for its intended use. As such, it is an essential requirement for any package of information submitted to regulatory agencies in support of new product marketing or clinical trial applications. Currently, there is no single source or final guideline on analytical method validation that helps analysts to perform validation in a systematic manner. Therefore, industry depends on the analyst's knowledge and experience to develop simple and efficient methods of analysis. The intention of this paper is to review regulatory requirements and role of the pharmacopeias and to study how analytical method development and validation are typically carried out at present, and to formulate this into a simple step by step approach. Such a template was not only used as the foundation of this research programme, but could also serve as a simple systematic guide for other practitioners and those new to the field. Furthermore, it was recognized that this protocol should satisfy the requirements of the most strategically important regulatory bodies.
