Exclusive Detection of Dimethyl Sulfide by a Pd–WO3 Sensor with the CuO/Al2O3 Filtering Overlayer

Abstract Selective detection of trace (weakly reducing) dimethyl sulfide (DMS) in highly humid exhaled breath using metal oxide semiconductor (MOS) sensors, with the presence of strong reducing H2S interference gas, is essential for the early diagnosis of hepatic diseases. Howeve...
