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.
