Petersburg International Economic Forum, and Anna Popova, Head of theįederal Service for Surveillance on Consumer Rights Protection and Human The Russian Federation and Executive Secretary of the Organizing Committee of The event was attended by Anton Kobyakov, Adviser to the President of If helium is used with the analysis, one can expect a decrease in the analysis time.SPIEF 2021 to follow rigorous health and safety protocolsĪ meeting was held in Moscow to discuss preparationsįor SPIEF 2021 in terms of compliance with all the necessary health and safety For this reason, we chose nitrogen as the carrier to show that it can be used with good results. Many locations worldwide testing for these compounds have difficulty acquiring low cost helium. The inertness of the SPB-20 resulted in good peak shape for all compounds, including the alcohols. The aroma compounds, isoamyl and active amyl alcohol, were separated almost to baseline. The ethanol matrix did not interfere, and all components were separated. We also assayed several real world beverage samples.įigure A illustrates the separation of the monitored compounds in a matrix of 40% ethanol in water. In this application, we used a 30m x 0.25mm ID, 1.0mm SPB-20 capillary column to separate 12 common components regularly monitored in alcoholic beverages. Traditional methods have employed packed column GC in fusel oil analysis. Collectively, these compounds are referred to as fusel oils. Compounds such as ethyl acetate, 1-propanol, isobutyl alcohol, and isoamyl alcohol are monitored as part of quality control in many beverages. Its separation from active amyl alcohol is considered critical if monitoring because these two compounds are normally produced together. At high levels, the aroma of isoamyl alcohol is unpleasant. At very low levels, this compound has a fruity, pleasant odor. Isoamyl alcohol, for example, is an aroma component in rum. To ensure consistency in finished product quality and flavor, many distilleries monitor the presence and relative levels of these compounds. These compounds impart many of the flavor and aroma characteristics familiar in certain beverages. In addition to ethanol and water, alcoholic beverages contain a variety of compounds that are produced during fermentation and or aging. In this application, we used a 30m x 0.25mm ID, 1.0μm SPB-20 capillary column to separate 12 common components regularly monitored in alcoholic beverages. Traditional methods for monitoring aroma components in alcoholic beverages have employed packed column GC in fusel oil analyses.
