Determination of Dimethoxymethane in Water by Purge-and-Trap Gas Chromatography/Mass Spectrometry
摘要
Abstract
[ Objective ] To establish a method for the determination of dimethoxymethane in water by purge-and-trap gas chromatography/mass spectrometry (GC/MS). [ Methods ] The dimethoxymethane in water were purged and trapped, then desorbed and analyzed by gas chromatography/mass spectrometry. The external standard method applied characteristic ions for quantification. [ Results ] The linearity of the method was good under the experimental condition of dimethoxymethane (r=0.999 5). The detection limit was 0.03 μg/L. The recovery rates were 95.2%-99.3%, and the relative standard deviations (RSD) were 2.18%-3.87%. [ Conclusion ] The purge-and-trap gas chromatography/mass spectrometry is a sensitive and accurate method for determination of dimethoxymethane in water.关键词
