近代各种成分分析和测定结构的方法在广泛的有机化学研究中已日益重要,但有机元素微量分析仍不失为有机化学研究中经常采用的一个基本方法,因为人们要从化学上识别一个化合物,一般总还是首先弄清它的元素组成。当然微量分析技术也不是停留在一个水平上,它的近代进展是比较快的。一、经典微量分析方法的近代化这里所谓的“经典”分析方法是指样品用量一般为几毫克的分析方法。它的近代讲展主要有两个趋向:一方面是趋向于 Modern methods of compositional analysis and structure determination have become increasingly important in a wide range of organic chemistry studies. However, trace element analysis of organic elements is still a common method used in organic chemistry because of the chemical recognition of a chemical compound The first is always to understand its elemental composition. Of course, trace analysis technology does not stop at a level, its recent progress is relatively fast. First, the modernization of classical micro-analysis method The so-called “classic” analysis method refers to the amount of the sample is generally a few milligrams of analytical methods. Its modern speaking exhibition mainly has two tendencies: On the one hand, it tends to be
