Now believed to be responsible for anaphylaxis to chemical substances, concentration of formaldehyde (HCHO) and volatile organic compounds (VOCs) given off by interior finishing materials and furniture is very low in residential spaces. To accurately measure this concentration, it is necessary to concentrate the air sample during sampling and to employ high-precision analyzers such as a gas chromatographic (GC) analyzer to obtain the results. Since these complicated sampling and analytical operations require a high-level of expertise, the development of an on-the-spot precise measuring instrument has long been awaited. Focusing on semiconductor odor sensors, we have been studying simplified methods of measuring total volatile organic compounds (TVOC) in a room. we have developed a simplified technique of pinpointing high chemical emission areas using the odor sensor. This paper reports the technique, including practical examples.
