Abstract
Gas chromatography/mass spectrometry and liquid chromatography/mass spectrometry provide a useful technical platform for analyzing environmental chemicals. Many measurement methods have been developed on this platform based on the present day needs. Simultaneous determination methods of substances such as pesticides, volatile organic compounds, polycyclic aromatic hydrocarbons, and persistent organic pollutants have been developed corresponding to their increase in the environment. One of the recent topics is the elucidation of structures of unknown environmental chemicals by analyzing their exact masses.
