本文介绍了电子鼻在尿液分析中的可能应用。与在液体中操作的传感器和生物传感器的常规应用相反，这里讨论的方法利用气体传感器执行顶部空间的分析。该应用程序涉及肾脏疾病患者的尿液样本;其中一些样本含有微量血液。结果表明，该电子鼻能有效区分含血样品，前3个主成分与血液含量之间存在线性相关关系，并能较好地检测样品的pH值和比重。
In this paper the possible application of an electronic nose to the analysis of urine is presented. In contrast with the conventional applications of sensors and biosensors operating in liquid, the approach discussed here makes use of gas sensors performing an analysis of the headspace. The application deals with urine samples from patients affected by kidney diseases; some of the samples contained traces of blood. Results show the possibility of distinguishing the samples containing blood from the others, and a linear correlation between the first three principal components and the blood content was found. Furthermore, the electronic nose matched with a suitable neural network showed good performance in measuring the pH and the specific weight of the samples.
