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.

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 enclosure...read more.

Chemistry

What is Chemistry?

It is the branch of science which deals with the study of composition, properties and interaction of matter.

Definition of Chemistry

Chemistry is the scientific study of matter and substances for how they combine, separate, react or interact with each other.

Types of Chemistry

Chemistry is generally (as per basic chemistry) classified into three classes i.e. Physical chemistry, Organic chemistry and Inorganic chemistry. 

1. Physical Chemistry

Physical chemistry is the branch of chemistry. Physical Chemistry utilizes applications of physics to chemical systems to understand their physical properties.
Physical chemistry is the study of atomic, subatomic, macroscopic, microscopic or particulate phenomena in chemical systems in terms of different laws and concepts of physics. Physical chemistry applies the principles and concepts of physics such as thermodynamics, force, time, energy, motion, statistical mechanics, quantum chemistry, dynamics and equilibrium.
Physical properties of different type of chemical substances can be studied on different scales like atomic, subatomic, macroscopic and microscopic........ read more 

2. Organic Chemistry

Organic chemistry is a branch of chemistry which involve the scientific study of structure, properties & reactions of organic species, compounds or organic materials, means matter have various forms found that contains carbon atoms. Study of structure of organic chemistry compounds includes use of spectroscopy techniques like IR Spectroscopy, Microwave Spectroscopy, NMR Spectroscopy, Mass Spectroscopy, X – Ray Diffraction, Electron Diffraction, Neutron Diffraction and other physical and/or chemical type of methods to examine chemical composition and chemical constitution of the organic chemistry compounds and materials to be analysed. This is article on what is organic chemistry at “chemistry notes info blog”. Study of properties of organic compound includes study of both physical properties as well as chemical properties of organic chemistry compounds, which uses the similar methods and also methods to evaluate the chemical reactivity to understand behavior of organic matter (organic sample) in its pure form (if when possible), otherwise in solution, mixture forms. Study of chemistry of organic reactions includes the searching their possibility through use in the preparations of goal molecule or compounds like natural products, medicinal drugs, polymers, solvents, etc.) by their chemical synthesis, also focused on the study of  reactivity’s of the individual organic molecules.... read more 

3. Inorganic Chemistry

Inorganic chemistry is the branch of chemistry, which deals with the study of inorganic compounds and organo-metallic compounds. Inorganic chemistry includes study of all chemical compounds excluding organic compounds (where, organic compounds are carbon based compounds, generally having carbon-hydrogen bonds i.e. C-H bonds. 

Example of Inorganic Compound

Salt Magnesium Chloride (MgCl2) is an ionic Inorganic Compound which contains magnesium-cations Mg2+ and chloride-anions Cl

Branches of Inorganic Chemistry

Descriptive Inorganic Chemistry
Descriptive inorganic chemistry based on the arrangement and ordering of compounds based on their properties.

Coordination Chemistry

Coordination chemistry is the branch of Inorganic chemistry which deals with the study of coordination compounds or coordination complexes. A coordination compound or coordination complex contains of a central atom or ion, which is generally metallic and is known as coordination center, and get surrounded by group of bounding molecules or ions, these surrounding molecules and ions are known as ligands.

Materials Science

Material science deal with the study of materials. Study of metals, semiconductors, polymers, ceramics, nanomaterials, biomaterials and many other form of materials comes under material science. A material scientist........... read more
