Determination of Algae Compounds in Drinking Water Using the SPME Arrow

The primary sources of the foul odor found in drinking water are the compounds 2-Methylisoborneol (2-MIB) and Geosmin. The compounds are formed from algal contamination. The low odor threshold of Geosmin and 2-MIB is so slight that even the faintest amount can produce an unpleasant aroma in drinking water. Standard Method 6040D describes a procedure for the detection of 2-MIB and Geosmin using Solid Phase Micro Extraction coupled with a Gas Chromatograph and Mass Spectrometer.
