Comparison of Novel SPME Arrow with Traditional SPME Fiber for the Trace-level Analysis of Taste and Odor Compounds in Drinking Water

Drinking water sources are sometimes contaminated by dying algae blooms which release “earthy” and “musty” odor compounds (2-methylisoborneol, or MIB, and geosmin). This odor is a major source of public complaints about unpleasant tasting drinking water. Although odor is only regulated by a secondary maximum contaminant level, it is critical for utilities and environmental laboratories to accurately identify and quantify specific compounds potentially involved in Taste and Odor (T&O) events. Therefore, a highly sensitive, robust, accurate, and high-throughput technique is required for the analysis of MIB and geosmin at concentrations down to their odor threshold levels (low ng/L). Solid Phase Microextraction (SPME) coupled with GCMS detection is a common analysis technique for these compounds; however, use of SPME Arrow in this application, which is more sensitive and robust than conventional SPME, has been limited. In this study, Standard Method 6040D was implemented for the analysis of MIB and geosmin employing SPME, and multi-point calibration curve, methodological detection limits (MDLs), and reproducibility experiments were conducted. The SPME Arrow device was run with the same method to compare limits of detection and throughput between the two extraction techniques. This workflow will help utilities and environmental labs in managing T&O events quickly and accurately
