study of separation and analysis of sample and identify its components.
Size Exclusion Chromatography In size exclusion chromatography ( molecular or gel filtration or gel permeation chromatography), molecules, and particles are separated. Small molecules penetrate the pores of the stationary phase, but large molecules do not. Because small molecules must pass through an effectively larger volume, large molecules are eluted first. This technique is widely used…
SCOPE OF CHEMISTRY Everything around us deals with chemistry. When we say a thing like a scope, we come to know that it’s a branch of science that is as old as mankind, and at the same time, it went through the evolution phases just like human beings. From the atmosphere to the sea, plants…
