The Thermo Scientific TRACE GC Ultra is applied for the analysis of vanillin from a cola soft drink. The sample was prepared using Thermo Scientific SOLA HRP solid phase extraction (SPE) cartridges, and the separation was performed on a Thermo Scientific TraceGOLD TG-WaxMS A GC column, with flame ionization detection.

建立了婴幼儿配方奶粉中香兰素和乙基香兰素的气相色谱测定方法。本方法步骤简单、快捷，精密度高，具有较好的分离度，杂质干扰少，测定结果准确可靠，灵敏度高，是测定婴幼儿配方奶粉中香兰素、乙基香兰素的较好的方法。

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.
