Under what conditions does the linear relationship of fluorescence quantitative analysis hold?
Quantitative analysis originated from a branch of analytical chemistry. There are different methods to determine the content of each component in a substance, which can be divided into three categories: gravimetric analysis, volumetric analysis and instrumental analysis. Due to the different amounts of the analyzed samples and the tested components, they can be divided into constant analysis, semi-micro analysis, micro analysis, ultra-micro analysis and micro analysis.

meaning

Quantitative analysis refers to the analysis of the quantitative relationship between the components or properties of the studied object; You can also quantitatively analyze and compare some properties, characteristics and relationships of several objects, and the results of the research are also described by "quantity".

theory

The theoretical cornerstone of quantitative analysis is positivism. From the logical process of research, quantitative analysis is close to the research of hypothesis-deduction method, which not only retains the characteristics of attaching importance to observation experiments and collecting empirical data, but also attaches importance to deductive reasoning of logical thinking. The application of hypothesis combines observation experiment and mathematical deduction. Because of this, quantitative analysis often emphasizes the objectivity and observability of physical objects, the interrelationship and causality between phenomena and variables, and requires researchers to strive for objectivity and ethical neutrality in their research.

way

There are many quantitative analysis methods, but they are often programmed in application. Such as experiment, observation, interview, social measurement,
