Analytical Chemistry is a branch of chemistry under science which deals with the analysis of different substances. It determines the chemical composition and the properties of various products. In a simple way, this field of chemistry is all about the art as well as the science of modifying as to what matter exactly consists. It is also called to as chemical analysis.
Most of the techniques of analytical chemistry mainly concentrate on the instrumental methods which involve electrical and optical instruments. The quantity of light that is emitted or absorbed by gas photons can be determined by this method. In the same way, the chromatography also uses the chemical analysis methods for the determination of the concentration of its components.
Branches of Analytical Chemistry
Two sub-branches are coming under analytical chemistry namely quantitative analysis and qualitative analysis which are explained as follows. These two methods form backbone of many educational labs of analytical chemistry.
Quantitative analysis- Quantitative Analysis is a method of determining the absolute or relative quantity regarding the concentration of one or more substances present in a sample.
For example, Take a sample of the unknown solid substance. The chemists first use “qualitative” methods to identify what type of compound is present in the sample; then he adopts the quantitative analysis procedure to determine the exact amount or the quantity of the compound present in the sample.
Some of the Quantitative analysis includes Gravimetric Analysis and Volumetric analysis.
Qualitative analysis- Quality means the standard or the feature of one substance. Hence Qualitative analysis method deals with the determination of the quality of a particular compound, irrespective of its quantity or concentration. In simple words, the qualitative analysis does not measure the amount of the substance but measures the quality of that material. One of the best examples of this type of method is the observation of a chemical reaction, whether the will be a color change or not.
The qualitative analysis method can be measured in different ways such as Chemical tests, flame tests, etc.
Importance of Analytical Chemistry
Analytical chemistry is the branch which is taught in almost all schools and colleges. But the applications of it are made in pharmaceutical industries, food factories, chemical industries, agricultural industries and in scientific laboratories. The tools used for this purpose is quite expensive which one cannot afford in the home.
All the foods which we buy such as medicines, cosmetics, chemicals undergo the process of quality and Quantitative tests before reaching you.
Applications of Analytical Chemistry
Analytical Chemistry finds its many applications coming in different fields of science and technology.
- In the field of agriculture, it is employed for testing of soil, water testing and testing of harvested crop.
- In the medical field, it is used in the testing of serum cholesterol, blood glucose levels, and urine ketones.
- It is employed in the process of chromatography where the blood samples of a person are determined.
- It has its other applications in the field of forensics, clinical analysis, bioanalysis, environmental analysis, materials analysis, etc.
