Verification and validation (also abbreviated as V&V) are independent procedures that are used together for checking that a product, service, or system meets requirements and specifications and that it fulfills its intended purpose. [1] These are critical components of a quality management system such as ISO 9000. The words "verification" and ...
Quality management systems usually require full documentation of the procedures used in a test. The document for a test method might include: [7] [8] descriptive title; scope over which class(es) of items, policies, etc. may be evaluated; date of last effective revision and revision designation; reference to most recent test method validation
Common validation characteristics include: accuracy, precision (repeatability and intermediate precision), specificity, detection limit, quantitation limit, linearity, range, and robustness. In cases such as changes in synthesis of the drug substance, changes in composition of the finished product, and changes in the analytical procedure ...
In analytical chemistry, cross-validation is an approach by which the sets of scientific data generated using two or more methods are critically assessed. [1] The cross-validation can be categorized as either method validation [ 1 ] or analytical data validation.
In chemistry, a chemical test is a qualitative or quantitative procedure designed to identify, quantify, or characterise a chemical compound or chemical group.
Retrosynthetic analysis is a technique for solving problems in the planning of organic syntheses.This is achieved by transforming a target molecule into simpler precursor structures regardless of any potential reactivity/interaction with reagents.
There are different reasons for performing a round-robin test: determination the reproducibility of a test method or process; verification of a new method of analysis. If a new method of analysis has been developed, a round-robin test involving proven methods would verify whether the new method produces results that agree with the established method.
Test validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure.In the fields of psychological testing and educational testing, "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests".
