From qualitative to quantitative measurement of small microplastics using multi-detector field flow fractionation coupled offline to microscopy and raman spectroscopy

Summary

This study developed an analytical method combining multi-detector field flow fractionation with offline microscopy and Raman spectroscopy to move from simply identifying microplastics to accurately measuring their quantity in small size ranges. Improved quantification methods are critical because current inconsistencies in measurement approaches make it difficult to set health-based exposure limits or compare contamination levels across studies.
