Analytical Coverage

ANALYTICAL COVERAGE

            Analytical chemistry is the science of obtaining, processing, and communicating information about the composition and structure of matter. In the other words, it is the art and science of determining what matter is and how much of it exist.Analytical chemists perform qualitative and quantitaive analysis, use the science of sampling, defining, isolating, concentrating and  preserving samples, set errors limits, validate and verify results through calibration and standarization. They also perform separation by differential chemical properties, create new way to make a measurement, interpret data in proper context and communicate the result.

            Analytical chemistry are employeed in all aspects of chemical research in industry, academia, and government. They do basic laboratory research, develop processes and products, design instruments used in analytical analysis. Teach, and work in marketing and law. Analytical chemistry has many contribution to many fields of science.

1.      Content Analysis

Content analysis is the main section of analytical chemistry. Content analysis will investigate about “what is the component contain in a sample” and “how much the contents present in the sample”. So, we can say that there are two analysis, qualitative analysis and quantitative analysis. Qualitative analysis will give the information about what kind of compound contain in the sample. Quantitative analysis will give information about the quantity of each compound contained in the sample. It also investigate the separation of matter by simple method or classical separation method and some modern separation method using non mechanical engine.Most of the separation is based on physical properties. Some of separation alsoby chemical reaction.

2.      Structural Analysis

Stryuctural analysis is development of question “what is the component contain in a sample”.Stuctural analysis determine by the modern analytical chemistry like mass spectrometry, GC-MS,  LC-MS, and NMR. In this part, we can determine the chemical stucture of chemical uncharacterised substance. We know deeper about the physical and chemical properties of each compound contained in the sample.

3.      Distribution Analysis

Distribution analysis usually used in heterogenous materials. Materials contain more than one substance will have different concentration in every parts of materials. If we know the parts which has highest concentration of certain substances, the separation process will be more efficient in time and work. Beside that, distribution analysis can be described as three dimentional, and the expansion of distribution analysis is on the study of science area. It very useful in develop new material which more useful.

4.      Process Analysis

Processs anlytical chemistry is similar to process analytical technology, it has a origins as a specialized form of analytical chemistry used for process manufacturing. Process analytical chemistry is the aplication of  analytical chemistry with specialized techniques, algorithms, and sampling equipment for solving problems related to chemical processes. The chemical processes are for production abd quality control of manufactured products, and process anlytical technology is used to determine the physical and chemycal properties of the desired products during a manufacturing process.

     Process analysis initially involved sampling the variety of process streams or webs and transporting samples to quality control or central analytical service laboratories. Time delay for analytical results due to sample transport and analytical preparation step negated the value of many chemical analyses for purposes other than product release. Over time it was understood that real-time measurements provided timely information about a process, which was for more useful for high efficiency and quality.The development of development of real-time process amalysis has provided information for process optimization during any manufacturing process.
