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.
EST Analytical has been helping labs achieve their analytical goals for over 30 years. Our vision is to engineer reliable laboratory instruments that enable partners to make the world a better place.
To help labs excel we offer Application Notes across our entire product line. They are a resource that explains the technology, performance, and abilities of our products as used against certain methodologies and or applications.
Whether your needs center around a USEPA method, an ASTM Standard, or a sample matrix-based outcome EST has you covered. If you don’t see the technical direction you need, simply contact us. We also offer sample analysis in our onsite Applications Lab.
