A spectrophotometric analysis of the absorption
Spectrophotometric process analysis the fundamental principle of spectrophotometric analyzers is based on the fact that molecules in a process stream absorb light (more in general, electromagnetic energy) at specific frequencies in a stream of known composition, it is possible to select one or more electromagnetic spectrum. Spectrophotometric analysis by optical absorption is based on the absorption of electromagnetic radiation that is proportional to the amount of the element, ion, compound or molecule being analyzed in the sample.
