Raman Spectroscopy can be used for more than just higher education and university research. The technique has applications as far reaching as environmental protection and water decontamination. 

​

Raman spectroscopy has emerged in the environmental engineering arena as one of the fastest and most cost effective ways to detect pollutants in water [1]. Dozens of companies have employed it to detect the presence of impurities (e.g. E. Coli) in our water supply and help keep it safe for us to drink [2]. 

​

That is not the only positive impact Raman is capable of. The field of air pollution control has felt its effects as well. Raman microspectrometry has been used to analyze and acquire data about aerosols [3], which comprise most common air pollutants. This has been used to ​slow the rate of global warming and prevent respiratory diseases.
