Aroma Component Analysis Using Nexis GC-2060

This guide details the analysis of aroma components in alcoholic beverages using the Nexis GC-2060 gas chromatograph system equipped with a Multi-Mode Inlet (MMI) and MonoTrap silica monolith sorbent. It outlines the capabilities of the MMI, which supports various injection methods, including thermal desorption/extraction, allowing for efficient analysis without the need for dedicated sample-preparation equipment. The document describes the methodology for collecting aroma components from sake and beer samples, emphasizing the ease of use and rapid analysis cycle times achieved through the MMI's cooling capabilities. Results from the analysis demonstrate the differences in aroma profiles between regular and daiginjo sake, as well as among different beer styles, highlighting the effectiveness of the MonoTrap in capturing volatile components. The findings provide insights into the aroma characteristics of these beverages, showcasing the potential for detailed qualitative and quantitative analysis in food science applications.
