Successful discrimination of 14 representative liquors (including scotch, bourbon and rye whiskies, brandy, and vodka) was achieved using a 36-element colorimetric sensor array comprising multiple classes of cross-reactive, chemically responsive inks. In combination with a palm-sized image analyzer, the sensor array permits real-time identification of liquor products based on vapor analysis within 2 min. Changes in sensor spot colors before and after exposure to the vapors of the liquors that are partially oxidized as they are pumped over the sensor array provides a unique color difference pattern for each analyte. Facile identification of each liquor was demonstrated using several different multivariate analyses of the digital data library, including principal component, hierarchical cluster, and support vector machine analysis. The sensor array is also able to detect dilution (i.e., “watering”) of liquors even down to 1% addition of water. This colorimetric sensor array is a promising portable adjunct to other available techniques for quality assurance of liquors and other alcoholic beverages.

用于识别酒的手持式光电鼻
使用包含多种类型的交叉反应性，化学响应性油墨的36元素比色传感器阵列，可以成功区分14种代表性酒（包括苏格兰威士忌，波旁威士忌和黑麦威士忌，白兰地和伏特加）。结合手掌大小的图像分析仪，该传感器阵列可在2分钟内基于蒸汽分析实时识别酒类产品。暴露于部分汽化的液体蒸气之前和之后，传感器专色的变化在泵送至传感器阵列上方时为每种分析物提供了独特的色差模式。使用数字数据库的几种不同多元分析方法（包括主成分，层次聚类和支持向量机分析）证明了每种酒的简便鉴定。传感器阵列还能够检测液体的稀释（即“浇水”），即使加水量低至1％。该比色传感器阵列是对酒类和其他酒精饮料质量保证的其他可用技术的有前途的便携式附件。
