酒中除含大量的乙醇和水外,還含有醇、酯、酸、羰基化合物、縮醛和酚類,其中以醇和酯含量為主。酒中甲醇、雜醇油也為衛(wèi)生監(jiān)測(cè)的重要指標(biāo)。目前氣相色譜作酒的分析文獻(xiàn)報(bào)道已很多,有DNP柱,PEG柱,GDX-102柱,有機(jī)擔(dān)體402柱,有機(jī)擔(dān)體403柱等。
浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司在用有機(jī)擔(dān)體403工作的基礎(chǔ)上,探討了GDX-103用于酒的色譜分析,結(jié)果表明,GDX-103對(duì)酒中主成分分離效果好,分析速度快,峰面積與其濃度有良好的線性關(guān)系,結(jié)果再現(xiàn)性較jia。

In addition to a large amount of ethanol and water, wine also contains alcohols, esters, acids, carbonyl compounds, acetals and phenols, of which alcohols and esters are the main ones. Methanol and fusel oil in wine are also important indicators for health monitoring. At present, there are many literature reports on the analysis of alcohol by gas chromatography, including DNP column, PEG column, GDX-102 column, organic support 402 column, organic support 403 column, etc.
On the basis of using organic support 403, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. explored the use of GDX-103 for chromatographic analysis of wine. The results showed that GDX-103 had good separation effect for main components in wine, fast analysis speed, good linear relationship between peak area and concentration, and good reproducibility of the results.
