Olive oil geography by GC-IMS analysis

53 olive oils from Spain (20), Italy (20) and Greece (13) of extra virgin quality, harvested during the 2014/2015 season, were kindly supplied by Coop Switzerland (Basel, Switzerland). Authenticity was verified by the supplier by chemical and isotope analysis. Olive oil samples were analysed by headspace GC-IMS. The setup includes an Agilent 6890N gas chromatograph (Agilent Technologies, Palo Alto, USA), coupled with a standalone ion mobility spectrometer (Gesellschaft für Analytische Sensorsysteme mbH, Dortmund, Germany). Measurements were carried out in triplicates. Binary files (*.mea format G.A.S. Sensorsysteme m.b.H., Dortmund, Germany)本数据集包含53份特级初榨橄榄油样本，其中西班牙产20份、意大利产20份、希腊产13份，均采集于2014/2015收获季，由瑞士合作社（Coop Switzerland，瑞士巴塞尔）惠赠。样本真实性已由供应商通过化学分析与同位素分析验证。 采用顶空气相色谱-离子迁移谱（headspace GC-IMS）对橄榄油样本开展分析。实验装置搭载安捷伦6890N气相色谱仪（Agilent Technologies，美国帕洛阿尔托），并连接独立式离子迁移谱仪（Gesellschaft für Analytische Sensorsysteme mbH，德国多特蒙德）。所有测量均进行三次重复实验。 数据集附带二进制文件，格式为*.mea，由德国多特蒙德的G.A.S. Sensorsysteme m.b.H.开发。
