Definition of Analytical Chemistry- Analytical Chemistry is the branch of chemistry deals with the study of material examination to separate out them into different components and identifying all components and how much these components present in material. There are different analytical methods and techniques to perform these tasks.
Analytical chemistry is all about, what an analytical chemist do in an analytical chemistry lab. And simply we can say that analytical chemistry is the branch of chemistry for qualitative analysis and quantitative analysis of compounds and mixtures by using different test methods and techniques like flame tests, chemical tests, precipitation, titration, chromatography, spectroscopy, separation, microscopy etc.
Types of Analytical Methods
Analytical chemistry uses two types of methods for analysis that are classical and modern methods. Classical methods are wet chemical methods while modern methods are instrumental methods. Classical analytical methods are further subdivided into two categories i.e. 1. Classical Qualitative Analytical Methods and 2. Classical Quantitative Analytical Methods. Similarly, Modern analytical methods are further subdivided into two categories i.e. 1. Modern Qualitative Analytical Methods and 2. Modern Quantitative Analytical Methods.
A. Classical Analytical Methods
1. Classical Qualitative Analytical Methods
Classical qualitative analytical methods uses precipitation, extraction, and distillation for separation purpose and differences in color, odor, melting point, boiling point, reactivity for identification purpose.
Some of the classical qualitative analytical methods are given below-
2. Classical Quantitative Analytical Methods
Classical quantitative analytical methods uses change in mass and volume for quantification of amount of particular analyte in analytical sample.
Some of the classical quantitative analytical methods are given below-
B. Modern Analytical Methods
1. Modern Qualitative Analytical Methods
Modern qualitative analytical methods uses chromatography, electrophoresis for separation purpose and uses instruments for identification purposes.
2. Modern Quantitative Analytical Methods
Modern quantitative analytical methods uses different instruments for quantitative analysis. These instruments are based on the principles of light or heat interaction, electric or magnetic fields. Generally a single modern instrument is enough for separation, identification and quantification of an analyte.
Modern analytical methods uses different instruments so we can say that modern analytical methods are Instrumental methods. And some of them are given below-
What is an Analytical Chemist ?
Analytical chemist is a chemical scientist who have all knowledge about analytical chemistry with other branches of chemistry like physical, organic and inorganic chemistry. They works in chemical labs or analytical chemistry laboratories to analyses different chemical compounds and mixtures.
What does an analytical chemist do ?
Analytical Chemist analyses samples to find out different analytes. They do different experiments in chemical labs to know about exact chemical component present in sample. Analytical chemist get all information from a sample means what that sample contains and how much contains. Nowadays analytical chemist do different researches to make analysis quick and more accurate by the use of modern techniques and modern equipment and advanced software’s.
Where does an analytical chemist work ?
Analytical chemistry work in chemical labs and analytical chemistry labs, means they conduct their experiment inside labs and then come back to analytical labs offices to interpret with experimental data.
