Dispersive Spectrophotometry Chemical Analysis Technique
Dispersive spectrometry (DS) methods make up a large number of ultraviolet, visible light and infrared spectroscopy systems. DS refers to the fact that the light or electromagnetic radiation passed through the sample (analyte) must pass through a monochromator either before or after the analyte, to describe the analyte’s absorption/transmission characteristic spectrum. A simplest monochromator is…

Spectrophotometry Instrumental Method of Analysis
Principle of Spectrophotometry Spectrophotometry is based on the electromagnetic radiation in the visible, ultraviolet and infrared ranges. According to the Quantum theory; the energy states of an atom or molecule are defined and change from one state to another, therefore, they would require a definite amount of energy. If this energy is supplied from an…
