How to Obtain a Large Absorbance Range

 
Absorbance spectroscopy is a molecular spectroscopy method that uses the wavelength dependent absorption characteristics of materials to identify and quantify specific substances.
Many molecules absorb ultraviolet or visible light emitted from a broadband light source. The absorbance is related to the concentration of the materials in the sample such that stronger absorbance means higher concentration.

There are many different approaches for measuring absorption spectra. The most common one is to point a generated beam of light at a …
