Application of Mass Spectrometry in Environmental Field is setfor the graduates who major in Environmental Science and Engineering. It is an optionalcourse and the total hour is 48. The objectives of this course are to helpstudents (1) master basic knowledge of mass spectrometry, such as GC/LC-MS,GC/LC-MS/MS, high-resolution mass spectrometry, imaging mass spectrometry; and(2) learn how to apply basic theories and methods of mass spectrometry toanalyze environmental problems related to xenobiotics and endogenous chemicalsand to develop solutions incorporated with exposome and metabolomics foraddressing the problems.
