Abstract
: A quality control material (QCM) for the analysis of volatile compounds in alcoholic beverages was developed. The problems of the development and production of QCM were investigated. The seven water-ethanol solutions, containing 9 volatile compounds (acetaldehyde, methyl acetate, ethyl acetate, methanol, propan-1-ol, propan-2-ol, 2-methylpropan-1-ol, butan-1-ol and 3-methylbutan-1-ol) with a concentration range from 1.20 to 5000 mg/L of anhydrous ethanol were prepared and studied according to the ISO Guide 80 and ISO Guide 35 in order to prove their stability over 6 months. The algorithm for the assessment of uncertainty associated with the characterization of QCM was developed. The studies were carried out by validated direct gas chromatography (GC) method with flame ionization detection (FID), based on using ethanol as an internal standard. The expanded relative uncertainty of QCM does not exceed 4.5 %.
