白酒中的微量成分的含量高低直接影响着白酒的风格。本方法以乙酸正丁酯 为内标，以氢火焰离子化为检测器，建立了白酒中12种微量成分的定量方法。本方法克服了常规法测定白酒中微量成分操作繁琐、时间长的缺点，实现了较好的分离效果和实验精密度。

The Thermo Scientific Triplus 300 Headspace Autosampler has been coupled to the Thermo Scientific Trace 1310 Gas Chromatograph for the analysis of 2,3-pentanedione and 2,3 butanedione in beer according to the method issued by the European Brewery Convention in 1999. One critical point of this method is the need to incubate the samples at 35°C. In this study the Triplus 300 HS has been successfully operated at a constant temperature of 35°C without any cryogenic device.

The Thermo Scientific Acclaim 120 C18 column is used for the analysis of vanilla extract. With an analysis time of under 16 minutes, the Thermo Scientific Acclaim 120 C18 column provides separation approximately 4 times faster than that by AOAC Official Method 990.25.

The AOAC Official Method 990.25 takes over 1 hour to run. In this work the Thermo Scientific Acclaim RSLC C18 column has improved selectivity and a much shorter run time. Using well-known geometric scaling rules, the assay can be accelerated sixfold. Doubling the flow rate accelerates the analysis 12-fold, with no sacrifice in the quality of the separation.

The Thermo Scientific Acclaim PA2 3 µm column is used to separate the components of artificial vanilla by HPLC-UV. With a total run time of less than 3.5 minutes the method allows fast detection of the components present.
