6. Applications in: Environmental Analytics (fine particles)
AI summary Read the abstract
This chapter reviews the application of micro-Raman spectroscopy to environmental analytics, particularly for identifying fine particles including microplastics. The author discusses advances in instrumentation that have reduced costs and increased throughput, making Raman-based microplastic identification more practical. The piece highlights Raman spectroscopy as a growing tool for characterizing plastic particles in environmental samples.
Micro Raman spectroscopy has been applied very early in environmental analytics. However, until now the field of application is quite limited. The main reasons for the low acceptance are high cost of the method and the low throughput. New developments in technology lead to cheaper instrumentation. Automation of Raman microscopy of particles might be a solution for a higher throughput and a broader application in environmental analytics. A more detailed analysis of aerosols and microplastic is good examples that could benefit from this development.
