Geosmin과 2-MIB의 GC/MS 분석을 위한 전처리 방법 비교 연구 = Comparison Study of Pretreatment Methods for GC/MS Analysis of Geosmin and 2-MIB

다국어 초록 (Multilingual Abstract)

Geosmin and 2-methylisoborneol are representative odorous compounds that smells like mud or mold after rain, and are secondary metabolites generated by various organisms such as blue-green algae and actinomycetes. These substances, which are detected in raw water and purified water, are odor substances that have not been found to be harmful to the human, but induce an unpleasant taste and odor in tap water and cause distrust in drinking. Therefore, research on the cause and removal methods is continued, and a sensitive and accurate detection method is required. In this study, three pretreatment methods(LLE, SPE, HS-SPME) and SPME arrow were compared for the detection of Geosmin and 2-MIB. In the four methods, the limits of quantitation were 0.2-0.8 ng/L for Geosmin and 0.6-1.1 ng/L for 2-MIB. The accuracy and precision of all four methods met the target values for quality control, but the HS-SPME and the SPME Arrow showed the most satisfied results.
