Is it really necessary to validate an analytical method or not? That is the question

Area of Science:

• Analytical Chemistry
• Method Development and Validation

Background:

• Method validation is a critical aspect of chemical analysis.
• There is a noted deficiency in awareness and understanding of method validation principles among analytical chemists.
• Existing literature on method validation is often underutilized, and some analysts perceive it as requiring external collaboration.

Purpose of the Study:

• To highlight the importance of method validation in analytical chemistry.
• To address the poor awareness and understanding of method validation requirements.
• To clarify the scope and application of method validation.

Main Methods:

• Review of existing literature and common practices in analytical chemistry.
• Identification of barriers to understanding and implementing method validation.
• Analysis of the definition and application of method validation.

Main Results:

• A significant gap exists in the practical application and comprehension of method validation among analytical chemists.
• Inconsistent terminology and definitions across different analytical sectors hinder understanding.
• Method validation is specific to a defined protocol, analyte, concentration range, test material, and purpose.

Conclusions:

• Method validation requires a clear understanding of its importance, scope, and execution.
• Standardized terminology and clear fitness-for-purpose criteria are necessary for effective method validation.
• Validation must ensure the analytical method is adequate for its intended purpose across specified conditions.
