The chapter also explains how to run a robustness test and how to evaluate the findings.
Chapter 8: Method Optimization
Chapter 8 of the handbook provides detailed information on the process of method optimization for pharmaceutical analysis. The chapter discusses the various techniques that can be used to optimize a method for pharmaceutical analysis, including the use of different analytical conditions, the use of different sample preparation techniques, and the use of different statistical methods for data analysis. The chapter also provides information on how to document the results of a method optimization study.
Chapter 9: Qualification of Analytical Instruments
The handbook's Chapter 9 contains in-depth information on the process of certifying analytical equipment for pharmaceutical analysis. The chapter examines the different elements that must be addressed while certifying analytical equipment, such as the instrument's accuracy and precision, detection and quantification limitations, and linearity and range. The chapter also discusses how to document the findings of an instrument qualification study.
Chapter 10: Stability Studies
Chapter 10 of the handbook provides detailed information on the process of stability studies for pharmaceutical analysis. The chapter discusses the various factors that can affect the stability of a pharmaceutical product, including temperature, humidity, and light exposure. The chapter also provides information on how to conduct stability studies for pharmaceutical products and how to document the results.
Chapter 11: Method Validation for Biotechnology Products
Chapter 11 of the handbook focuses specifically on method validation for biotechnology products. The chapter discusses the unique challenges that arise when validating methods for biotechnology products, including the complexity of the product and the potential for product variability. The chapter also provides information on how to validate methods for biotechnology products and how to document the results.
Chapter 12: Analytical Quality by Design
Chapter 12 of the handbook provides detailed information on the concept of analytical quality by design (AQbD). The chapter discusses the importance of AQbD in ensuring the quality of pharmaceutical products and the role of method validation in implementing AQbD. The chapter also provides information on how to implement AQbD in the development and validation of analytical methods for pharmaceutical products.

Method Validation in Pharmaceutical Analysis: A Guide to Best Practice
Adopting a practical approach, the authors provide a detailed interpretation of the existing regulations (GMP, ICH), while also discussing the appropriate calculations, parameters and tests. The book thus allows readers to validate the analysis of pharmaceutical compounds while complying with both the regulations as well as the industry demands for robustness and cost-effectiveness.
Following an introduction to the basic parameters and tests in pharmaceutical validation, including specificity, linearity, range, precision, accuracy, detection and quantitation limits, the text focuses on a life-cycle approach to validation and the integration of validation into the whole analytical quality assurance system. The whole is rounded off with a look at future trends.
With its first-hand knowledge of the industry as well as regulating bodies, this is an invaluable reference for analytical chemists, the pharmaceutical industry, pharmaceutics, QA officers, and public authorities.
