In this article we will discuss about:- 1. Principle of Infrared Spectroscopy 2. Equipment of Infrared Spectroscopy 3. Types 4. Sample Preparation 5. Uses and Applications. Principle of Infrared Spectroscopy: IR spectroscopy works on the principle that molecules absorb specific frequencies that are characteristic of their structure. At temperatures above absolute zero, all the atoms in molecules are in continuous vibration [...]

Apparatus of Differential Thermal Analysis: The DTA apparatus consist of the following: 1. Sample holder, usually ceramic, nickel, or platinum. 2. Furnace with a temperature controller to provide a constant rate of heating. 3. Thermocouples for the measurement of [...]
In this article we will discuss about:- 1. Principle of Transmission Electron Microscopy 2. Components of Transmission Electron Microscopy 3. Applications. Principle of Transmission Electron Microscopy: The transmission electron microscope can be compared with a slide projector. In a slide projector, light from a light source is made into a parallel beam by the condenser lens; this passes through the [...]
