    PRACTICAL 7 TITLE : DETERMINATION OF ERYTHROSINE CONCENTRATION USING UV- VISIBLE SPECTROPHOTOMETER INTRODUCTION In chemistry‚ spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. It is more specific than the general term electromagnetic spectroscopy in that spectrophotometry deals with visible light‚ near-ultraviolet‚ and near-infrared‚ but does not cover time-resolved spectroscopic techniques. Spectrophotometry
