What is Analytical Science? 什么是分析科学?





What is Analytical Science?


The above description of analytical chemistry provides an overview of the discipline of analytical chemistry. There have been various attempts to more specifically define the discipline. The late Charles N. Reilley said: "Analytical chemistry is what analytical chemists do" The discipline has expanded beyond the bounds of just chemistry, and many have advocated using the name analytical science to describe the field. This term is used in a National Science Foundation report from workshops on “Curricular Developments in the Analytical Sciences.” Even this term falls short of recognition of the role of instrumentation development and application. One suggestion is that we use the term analytical science and technology.


The Federation of European Chemical Societies held a contest to define analytical chemistry, and the following suggestion by K. Cammann was selected.

Analytical Chemistry provides the methods and tools needed for insight into our material world … for answering four basic questions about a material sample:

● What?

● Where?

● How much?

● What arrangement, structure or form?







The Division of Analytical Chemistry of the American Chemical Society provides a comprehensive definition of analytical chemistry, which may be found on their website. It is reproduced in most part here:

Analytical Chemistry seeks ever improved means of measuring the chemical composition of natural and artificial materials. The techniques of this science are used to identify the substances which may be present in a material and to determine the exact amounts of the identified substance.



Analytical chemists work to improve the reliability of existing techniques to meet the demands for better chemical measurements which arise constantly in our society. They adopt proven methodologies to new kinds of materials or to answer new questions about their composition and their reactivity mechanisms. They carry out research to discover completely new principles of measurement and are at the forefront of the utilization of major discoveries, such as lasers and microchip devices for practical purposes. Their efforts serve the needs of many fields:


- In medicine, analytical chemistry is the basis for clinical laboratory tests which help physicians diagnose disease and chart progress in recovery.

- In industry, analytical chemistry provides the means of testing raw materials and for assuring the quality of finished products whose chemical composition is critical. Many household products, fuels, paints, pharmaceuticals, etc. are analyzed by the procedures developed by analytical chemists before being sold to the consumer.

- Environmental quality is often evaluated by testing for suspected contaminants using the techniques of analytical chemistry.

- The nutritional value of food is determined by chemical analysis for major components such as protein and carbohydrates and trace components such as vitamins and minerals. Indeed, even the calories in a food are often calculated from its chemical analysis.

Analytical chemists also make important contributions to fields as diverse as forensics, archaeology, and space science.
