College of Plant Protection, Henan Agricultural University, Zhengzhou 450002,China; 2. Shunde Polytechnic College, Guangdong 528333, China) Abstract Gas chromatography-mass spectrum (GC-MS) and high pressure liquid chromatography (HPLC) are the two techniques most frequently used in research on chemical ecology. Drawing on the authors experiences, this paper discusses key points related to sample preparation, the principles of GC-MS and HPLC, how to select techniques for chemical analysis, the qualification and quantification of samples, and describes and discusses some examples in detail. Key words chemical analysis, GC-MS, HPLC, sample preparation, qualification and quantification 992 - GC-MS HPLC 样品制备要点 20 * 20203036 ** E-mail: fmyan@henau.edu.cn 204-0-20 204-03-06
