Goal of this application is to demonstrate the applicability of a modern, high-throughput valve-and-loop static headspace autosampler to obtain full compliance with the European Standard EN 13628-1, which specifies guidelines for the quantitative determination of residual solvents in flexible packaging by Multiple Headspace Extraction methodology. The Thermo Scientific Trace1310 GC coupled with the Triplus300 HS have been used for this purpose.

本文采用赛默飞世尔气相色谱质谱联用仪测定白酒中的微量成分，白酒直接进样，采用内标法定量，方法简单，定量准确，重现性好。

本实验采用HPLC-CAD 检测器对庆大霉素有关物质即其C组分进行测定，实验精密度、重复性、线性都较好。与蒸发光测定方法比较，不取对数线性相关系数就可以达0.998，从而计算结果不用进行对数转换，大大简化了含量计算过程。对照品和供试品溶液色谱图中C2 和C2a 之间的峰为小诺霉素峰，它们三个之间的分离度大于2.0，由于该化合物为庆大霉素C 组分中的次要成分所以未对其进行分析。

The Thermo Scientific Dionex UltiMate 3000 system is applied for the reaction monitoring separation of avorvastatin and its impurities. The separation was performed on a Thermo Scientific Accucore PFP column, with UV detection at 248 nm and a total run time of 18 minutes.

The Thermo Scientific HPLC system is applied to determine active ingredients in sunscreen lotion, which has been prepared for analysis by liquid-liquid extraction. The separation was performed on a Thermo Scientific Acclaim Mixed-Mode WAX-1 column in normal-phase mode with UV detection at 305nm.
