Focal plane array detector-based micro-Fourier-transform infrared imaging for the analysis of microplastics in environmental samples
Environmental context Microplastics are of increasing environmental concern following reports that they occur worldwide from the arctic to the deep sea. However, a reliable methodology that facilitates an automated measurement of abundance and identity of microplastics is still lacking. We present a...
