Nanoplastics analysis with Nano-FTIR
AI summary
This study assessed microplastic detection using pyrolysis-gas chromatography/mass spectrometry (Pyr-GC/MS) for complex environmental matrices, optimizing instrument parameters for polymer identification and quantification. The research demonstrated that Pyr-GC/MS can reliably detect and quantify major plastic polymer types in sediment and biological samples, offering a complementary approach to particle-counting methods.
