EXPLAIN THE PRINCIPLE OF ULTRAVIOLET SPECTROSCOPY - AN OVERVIEW

explain the principle of ultraviolet spectroscopy - An Overview

Molecules smaller sized when compared to the pore measurement penetrate the beads and take for a longer time to elute, while more substantial molecules are excluded within the pores and elute far more swiftly. It is often utilised to determine the molecular bodyweight distribution of polymers and to separate biomolecules like proteins.The final cha
