Identification of various polymer masterbatches
Applications | | MetrohmInstrumentation
Polymers are fundamental materials in modern industry and daily life. Polymer masterbatches offer a cost-effective way to incorporate colorants and functional additives into plastics during manufacturing, enabling properties such as UV resistance, antistatic behavior, and antifogging.
This study established a spectral library of various color masterbatches and assessed the Metrohm Mira M-1 handheld Raman spectrometer’s ability to identify unknown samples rapidly and without sample preparation.
Measurements were performed with the Mira M-1 using a 785 nm laser and Orbital-Raster-Scan (ORS) technology in auto-acquisition mode. Samples, including white, red, yellow-orange, green, blue, and black masterbatches, were analyzed either in glass vials using a vial holder attachment or directly through plastic containers with a long working distance lens.
The constructed library enabled clear spectral differentiation among most masterbatches. Black pigments absorbed the laser fully, preventing analysis. Autonomous identification matched unknown samples to the library within seconds, although minor spectral contributions from container materials were noted.
The Mira M-1 provides rapid, nondestructive, and preparation-free identification of polymer masterbatches, supporting quality control, counterfeit detection, and efficient process monitoring in polymer manufacturing.
Future developments may include expanding spectral libraries to cover a broader range of additives, integrating chemometric and AI algorithms for improved pattern recognition, and embedding handheld Raman systems in production lines for real-time monitoring.
The handheld Mira M-1 Raman spectrometer reliably and quickly identifies color masterbatches in plastics, enhancing polymer analysis workflows without the need for sample preparation.
