Principle of UV-Visible Spectroscopy - Detailed Explanation
The Principle of UV-Visible Spectroscopy is based on the absorption of ultraviolet light or visible light by chemical compounds, which results in the production of distinct spectra. Spectroscopy is based on the interaction between light and matter. When the matter absorbs the light, it undergoes excitation and de-excitation, resulting in the ...

HPLC Chromatography Principle and Working Methodology
The principle involved in HPLC testing is the separation of compounds in a mixture more efficiently and also quickly than that of traditional column chromatography. Segregation of compounds is due to their relative differences in travel through the column on the application of pressure exerted through the mobile phase or carrying liquid.

Chromatography - an overview | ScienceDirect Topics
Chromatography. Chromatography is a physico-chemical method for separation of compound mixtures, based on the distribution of components between two phases, one of which is stationary (sorbent), and the other, mobile, flowing through a layer of the stationary phase. From: Chemical Analysis of Food: Techniques and Applications, 2012.

A DC machine is an electromechanical energy alteration device. The working principle of a DC machine is when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such as DC generator as well as DC motor.
