Single-column analysis of mold odorants and trihalomethanes using nitrogen carrier gas
1. Introduction
Musty odor-causing substances, produced by phytoplankton called cyanobacteria, and trihalomethanes (THMs), produced by the reaction of chlorine injected into the water purification process at water treatment plants with various organic substances in the water, are always closely monitored as indicators of health risks and quality degradation in water quality analysis.
In this report, we have investigated a method for measuring both musty odor compounds and trihalomethanes using the SPME-GC-MS method with nitrogen carrier gas and the single column. As a result of our investigation, we have found that it is possible to detect both substances with sufficient sensitivity and reproducibility at a concentration of 1/10 of the water quality standard, and we report this here.
