Raman Spectroscopy’s Signals and Future Continue to Get Brighter
Spurred by the passage of state legislation last fall, the Southern California Coastal Water Research Project issued a methodology for monitoring microplastics in drinking water. The California regulation was the first of its kind in the U.S. to address widespread microplastic pollution in the environment. In response, an international group of scientists came together to develop guidelines for implementing the regulation, and they identified Raman spectroscopy as a key technique for the...
