信息物质的化学分析技术

Chemical analysis techniques for infochemicals

化学生态学研究中最常应用的化学分析技术是气相色谱-质谱联用技术(GC-MS)和高压液相色谱技术(HPLC)。本文根据实践经验和体会,重点介绍样品制备要点、GC-MS和HPLC的基本原理、如何选择化学分析技术、信息化学物质定性和定量分析的要点以及示例等。

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.
