Comparison of Mold Odor Analysis in Water by Purge and Trap (PTC) and Solid-Phase Microextraction (SPME)
Abstract Taste and odor are important to consumers when it comes to drinking water. Two compounds that are responsible for many taste and odor issues are geosmin and 2-methylisoborneol. Both of these compounds are produced by microbes and have very low odor thresholds. Because of this, many drinking water laboratories require detection levels of below 10ppt. Analysis of these compounds is usually ...
