About validation of a method for the determination of volatile compounds in spirituous beverages using contained ethanol as a reference substance
Abstract
The paper proposes an algorithm for validating a modified internal standard method using ethyl alcohol contained in the test sample as a reference substance. It is shown that the method can be validated based on experimental data previously obtained in the laboratory during validation of the standard method in accordance with current standards. As a result, no additional financial, material, or labor costs are required to validate the proposed method. The new approach has been proposed for standardization as an official OIV method of analysis, and is currently under consideration as draft resolution OENO-SCMA 24-756 “Method for determination of volatile compounds in spirituous beverages of vitivinicultural origin using contained ethanol as a reference substance”
