Analytical Chemistry

Analytical Chemistry

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.

What is Analytical Chemistry ?

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-

     a)  Flame Test
b)  Chemical Test

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-

     a)  Gravimetric Analysis
b)  Volumetric Analysis

     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-

          a)  Spectroscopy
      b)  Mass Spectrometry
      c)  Electrochemical Analysis
     d)  Thermal Analysis
     e)  Chromatography
      f)  Electrophoresis
     g)  Microscopy

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.

Do you know ?

What is an analytical balance?

what is Analytical Balance
Analytical balance is a lab-instrument used to determine mass of any matter very precisely. These analytical balances are very sensitive and expensive lab-instruments, and also upon the accuracy and precision of analytical balance the accuracy of lab-analysis result depends so handle these balances very carefully. Generally used analytical balances are balances with the capacity of 100 gram to 200 gram and the sensitivity of 0.1 miligram to 0.001 miligram. For any quantitative chemical analysis there is need of analytical balance for the weighing of sample for analysis and weighing of reagents for solution preparation. Analytcal balance pan used to put sample on it is enclosed in a glass-fitted case, means analytical balance sensitivity requires that it to be protected by the draft shield or more.
