We present a compact and easy to handle instrument developed to perform rapid analysis of liquids utilizing an "electronic tongue" system. Briefly, the e-tongue used here is based on impedance measurements of an array of sensing units fabricated with ultrathin films of different materials deposited onto gold interdigitated electrodes. The instrument has the capability of measuring up to eight different sensor sets, each comprising an array of eight sensing units, and can perform a series of measurements in less than half of an hour. Additionally, there is a user-friendly software interface for instrument control, allowing the statistical correlation of samples using principal component analysis.
我们展示了一种紧凑且易于操作的仪器，该仪器是为利用“电子舌”系统对液体进行快速分析而开发的。简而言之，这里使用的电子舌基于对一系列传感单元的阻抗测量，这些传感单元由沉积在金叉指电极上的不同材料的超薄膜制成。该仪器能够测量多达八个不同的传感器组，每组包括一个由八个传感单元组成的阵列，并且可以在不到半小时的时间内进行一系列测量。此外，还有一个用于仪器控制的用户友好型软件界面，允许使用主成分分析对样品进行统计相关性分析。
