§12-1 Preface of mass spectrometric analysis
Mass Spectroscopy This is a powerful tool for the identification of materials. It relies of the production of ions from a parent compound and the subsequent charaderization of the patterns thd are produced. While it is a qualtative tool,it an be coupled with other methods. We'll look at some of the basic equipment and types of data obtained
质谱分析的基本原理:使所研究的混合物或单体形成离 子, ,然后使形成的离子按质荷比(masscharge ratio)m/z 进行分离。 → + M M
