Detection of polymer impurities in recycled plastics using chemometric analysis of ATR spectroscopy

Learn how the Specac Quest™ can be used to quickly identify impurities in your plastic materials.

As global concerns over plastic waste and landfill overflow grow, the need for efficient recycling solutions has never been greater. One critical challenge in plastic recycling is accurately identifying and separating different polymer types to ensure high-quality reuse. Despite best efforts, contamination remains a persistent issue—making precise impurity detection essential.

In this application note, discover how Specac used FTIR spectroscopy and chemometric analysis to effectively detect polypropylene (PP) impurities in polyethylene (PE). Learn how the Specac Quest™ single-reflection ATR is specifically designed for mid- and far-IR applications, featuring an advanced gold-coated, all-reflective optical design powered by Specac’s proprietary Synopti-Focal array technology.
