Geosmin (GSM) with an earthy odor resembling is often accompanied by 2-methylisoborneol (MIB), which caused the earthy and musty taste of drinking water. To detect trace GSM solution, we designed gas sensor by Surface-enhanced Raman Scattering (SERS) technology which has the capacity of single molecule detection. With our ultra-high sensitivity detection system, response range from 10 ppt to 10 ppb geosmin in ultrapure water was confirmed. Additionally, 100 ppt geosmin in tap water was detectable.
