Application Note: Comparing Compact NIR Spectrometers for Polymer Identification

Posted on: 
10 October 2025

How do you ensure rapid and reliable polymer identification in your process?

Near-infrared (NIR) spectroscopy is a powerful, non-destructive technology for quality control, recycling, and in-line monitoring. But with various compact spectrometers on the market, choosing the right one for your specific setup is critical.

Our new application note offers a direct performance comparison, using our Diffuse Reflectance Fiber Probe to analyze six common polymers. We investigated different spectroscopic methods to provide clear, actionable insights.

Key takeaways from our study:

Clear Discrimination: Both Fabry-Pérot and grating-based spectrometers can successfully discriminate between all six polymer classes.

Bulk vs. Granule: We found improved class separation in bulk measurements due to the averaging of scattering effects, a key consideration for in-situ analysis.

Performance Differences: While the Fabry-Pérot based spectrometer provided better class resolution in a simpler model, the grating-based system is often faster and better suited for rapid process control.

This research proves the feasibility of using compact spectrometers with fiber probes for robust polymer analysis.
