用于评估口臭的感官测试通常由牙科临床医生进行,尽管它是一项主观测试。因此,需要进行口臭测试来进行客观评价。口臭是由细菌代谢产生的挥发性硫化合物(VSC)引起的。在这项研究中,我们提出了一种使用石英晶体微天平(QCM)传感器阵列与预浓缩器相结合来区分硫化合物的方法。温度分布的调整、流路顺序的优化以及除湿过滤器的使用使得能够在高湿度条件下进行VSC测量。此外,主成分分析结果表明,使用传感器阵列输出模式可以分离出三种类型的VSC。
An organoleptic test for the assessment of halitosis is usually performed by a dental clinician, although it is a subjective test. Thus, a halitosis test for objective evaluation is required. Halitosis is due to volatile sulfur compounds (VSCs) produced by bacterial metabolism. In this study, we proposed a method for discriminating sulfur compounds using a quartz crystal microbalance (QCM) sensor array combined with a preconcentrator. The adjustment of the temperature profile, the optimization of the flow path sequence and the use of a dehumidification filter enabled VSC measurement under a high-humidity condition. Moreover, the result of principal component analysis indicated that three types of VSC were separated using the sensor array output pattern.
