How to use Purge & Trap for Determination of MIB Geosmin in Water

Young boy drinking water from a glass.

Algal contamination in drinking water is becoming a common problem. The primary compounds that result from this contamination are 2-Methylisobomeol (2-MIB) and Geosmin. These compounds cause a musty odor in water and since the odor of these compounds have a very low threshold for detection, small amounts of contamination can cause drinking water to taste and smell unpleasant. This application note will investigate the detection of 2-MIB and Geosmin down to a 1ppt level.
