Abstract

This study focus on the analysis of various plastic samples using the portable MEMS-FTIR spectrometer in both transmission and diffuse reflection modes operating at two resolutions of 10 nm and 16 nm. The analysis focuses on the mid-infrared region spanning from 2000 nm to 4600 nm. Many plastic samples have been differentiated such as Nylon, Polypropylene, Polystyrene, Acrylonitrile butadiene styrene, and colored High-Density Polyethylene. The results shows that transmission module is efficient for clear plastic samples sorting and diffused reflection module is efficient for opaque plastic samples sorting. The findings position the MEMS-FTIR spectrometer as a portable, cost-effective, and accurate solution for plastic analysis tasks, demonstrating versatility and potential advantages over traditional methods in the specified MIR range.
