前的临床诊断基于生物化学,物理学和微生物学方法。用于检测尿样中的化学成分或VOC的电子鼻系统旨在对不同的尿成分进行分类,以便能够准确地诊断疾病和其他成分。本研究使用来自马来西亚理工大学(UTM)健康中心的13名患者的尿液样本进行尿液分析。该研究的结果显示,6名患者检测出粘液异常,而只有1名患者检测出细菌异常,2名患者健康。使用Cyranose 320进行的试验表明,尿液中存在挥发性化合物。主成分分析(PCA)用于从用于尿液分析的32个传感器中提取第一和第二主成分。...
 

Detection of volatile compounds in urine using an electronic nose instrument

DOI:10.1109 / ICCEEE.2013.6633956

Current clinical diagnostics are based on biochemical, physics and microbiological methods. The electronic nose system used to detect chemical components or VOCs in urine sample is meant to classify different urine components so as to be able to diagnose diseases and other elements accurately. This study used urine sample from 13 patients from Universiti Teknologi Malaysia (UTM) health centre for the urine analysis. Findings from the study revealed that six patients tested abnormal with mucus while only one patient tested abnormal with bacteria and two healthy. The test conducted from using Cyranose 320 shows that volatile compounds were present in their urine. Principal component analysis (PCA) was used to extract first and second principal components from 32 sensors used for the urine analysis. The study suggests the possibility of using e-nose as an early detection system for illness such as diabetes and bacterial infections.
