Results of the estimation of the precision for determination of volatile compounds in alcoholcontaining products by gas chromatography: acetaldehyde, methyl acetate, ethyl acetate, methanol, isopropyl alcohol, propyl alcohol, isobutyl alcohol, butyl alcohol, isoamyl alcohol are presented. To determine the accuracy, measurements were planned inaccordance with ISO 5725 and held at the gas chromatograph Crystal-5000. Standard deviation of repeatability, intermediate precision and their limits are derived from obtained experimental data. The uncertainty of the measurements was calculated on the base of an “empirical” method. The obtained values of accuracy indicate that the developed method allows measurement uncertainty extended from 2 to 20 % depending on the analyzed compound and measured concentration.
