Analytical Chemistry

Analytical chemistry is the subject for the method and basic principle of studying and identifying of the composition, status, structure of matter as well as determination of related content. It is an important branch of chemistry subject. Analytical chemistry plays an important role in not only its own development but also in various fields related to the chemistry. We can say that all the practice of any human activity involving chemical phenomena is inseparable from analytical chemistry. Now, people have developed various kinds of different analytical methods, which can be classified based on an analysis task, analysis object, the basis of the analysis, requirement of the analysis and sample dosage. According to the analysis tasks, it can be divided into qualitative analysis, quantitative analysis and structural analysis. Task of qualitative analysis is to identify the elements, radicals, functional groups or compounds that constituting the substances; the task of the quantitative analysis is to determine the content of the related components in the sample; the task of structural analysis is to study the molecular structure or crystal structure of the material.
