New Method for Quantitative Determination of Volatile Compounds in Spirit Drinks by Gas Chromatography. Ethanol as Internal Standard

TL;DR

This paper introduces a new gas chromatography method using ethanol as an internal standard to directly measure volatile compounds in spirit drinks without prior alcohol strength measurement.

Contribution

It proposes a practical, accurate approach for analyzing volatile compounds in spirits using ethanol as an internal standard, simplifying laboratory testing procedures.

Findings

Method allows direct concentration measurement in mg/L of absolute alcohol.

Experimental validation confirms accuracy and practicality of the approach.

Eliminates need for separate alcohol strength measurement.

Abstract

The new methodical approach of using ethanol as internal standard in gas chromatographic analysis of volatile compounds in spirit drinks in daily practice of testing laboratories is proposed. This method provides determination of volatile compounds concentrations in spirit drinks directly expressed in milligrams per liter (mg/L) of absolute alcohol according to official methods without measuring of alcohol strength of analyzed sample. The experimental demonstration of this method for determination of volatile compounds in spirit drinks by gas chromatography is described.
